possible 360 build

Posted by: | Comments Comments Off on possible 360 build
I have a 2000 360 block here (Magnum engine) It had been completely rebuilt including hot tank, 30-thou overbore, new cam bearings and freeze plugs, polished crank, all new bearings, new oil pump, new roller lifters, and more. No line boring or anything like that though. this engine wound up a stack up of errors. It was a Craigslist "used engine" buy, that was rebuilt to replace the original 258K mile Magnum 360 that came out of my Durango. I had never heard it run upon buying, took it...

yet another 318 cam thread

Posted by: | Comments Comments Off on yet another 318 cam thread
78 Fury 2 door HT 55k original miles 2.76 rear, 904 trans. 2 bbl, still needs lean Burn to be removed. just fired it up today, fired right up. so far only mod from stock is true duals with Thrush welded mufflers (like the Flowbastards) with tails out to the bumpers. typical corner muffler shop exhaust.
I don't want to swap gears (yet anyway) (might) eventually look for a set of 3.08 or 3.21 gears for the 8-1/4.
Car is a slug off the line, absolutely loves cruising the highway at 70. will...

EQ Magnum head issues?

Posted by: | Comments Comments Off on EQ Magnum head issues?
I have bought 3 sets of EQ Mopar heads over the last 10 years, 2 of which went onto LA blocks with all the "conversion" parts// the custom pushrods, Magnum engine rockers, valve covers, etc. These were drilled with the LA intake pattern from the factory.
The 1st set was bought bare, and I fitted it with the best pieces cherry picked off of 5 cracked OEM Magnum heads' valves, springs and retainers, put onto an 83 318 in a 3/4 ton truck. Ground the valves and lapped them in. . the 2nd set was bought "fully dressed" and put onto an LA 360. and into a Ramcharger. Runs fine with no issues. both of these are carb'd applications.
not sure that means anything but thought I'd mention it
In both instances, there was a huge noticeable difference, in how the engine they were installed onto, ran.// though to be fair, in both cases they also got "1 step over stock" RV type cams along with the EQ heads......the 318 went from 2bbl to 4 bbl, and the Ramcharger went from that horrible late 80s TBI to a 4 bbl and "Mopar orange box" ignition at the same time, as well.


now the 3rd set.... actually went onto a Magnum 360 bottom end, otherwise 100% stock rebuild in an 01 Durango. only deviation was an 0.030 overbore and coated hypereuctic pistons. I had plans for a couple of bolt on upgrades once it was broken in// but never got that far.

A little backstory/ get a beer, some popcorn maybe some no-Doz..... sorry. PLEASE BEAR WITH ME//// ASKING FOR OPINIONS/ASSISTANCE I haven't been here in a while, things have been crazy. and not just with this Durango either.

I had bought this Durango 5-6 years ago, as a clean transplant from the South, no rust at all, came from Louisiana just a month before I got it. Had the highest miles on it of any vehicle I have ever bought, right off the bat. but it was CLEAN. it was a choice between either this one, or a black 01 a mile from home, with 100k less miles but a 4.7 engine and a "rebuilt" title. I wanted a 5.2/5.9 "or nothing". still haven't owned a 4.7 anything. This Durango was found on CL about 55-60 miles away. was a great vehicle for us from 214k (when I got it) until 250-some K miles when I started getting a chronic code for a cyl 6 misfire. Fought that for most of a year, thought I had it licked, then the bottom end started getting rattley. I had done a thorough tune-up, many sensors, had injectors rebuilt, went thru wiring harness, and more/ everything humanly possible from "outside" the combustion chamber. Until just before the end, the code would come up but engine didn't run like it had any sort of misfire. in the end, "it showed".

so figuring that my misfire must be internal, (yes I had done a compression test a few times while chasing "external engine" possibilities and it was always 150-ish) but I bought a used 360 from CL and proceeded to tear it apart completely, sent to a machine shop for "the treatment". Complete stock rebuild. Not wanting to get into paying someone to tune a computer for mods, I went back stock.
I rebuilt the trans at the same time. Brand new cat, muffler, tuneup, O2's, sent starter and alternator in for rebuild at local starter/alternator shop, everything. New fuel pump at same time, even. just because.

I thought I had my misfire licked, I had sent the computer in to one of those "computer rebuild" places. still had issues. went to a local boneyard and got another 01 Durango 5.9 brain. Start/quit. Start/quit. reminded me of the old ballast resistor issue. It was the damned "security" crap. So I sent the original brain and the junkyard brain back to the computer store. told them that between the 2, please get me 1 good working functional computer, that will run this damn truck. program junkyard brain for my VIN. They did as I asked, "n/c" because I was still having problems. Did what was asked for BOTH brains for free. said both had lifetime warranty, both ran fine on a "test truck" they had out behind the place. Upon the 2nd time sending them in, they apologized profusely for the problems with the original one, and made it known "in no uncertain terms" that the guy who had worked on my original brain "no longer works for us, you won't have issues with either one, very sorry". I guess that whatever had worked loose originally and was re soldered back in, had come loose again. being that the original had been into twice IDK if I can ever trust it again..... they hole sawed a hole in the computer housings and silicone the drilled out piece back in. IDK if that is "normal procedure" or not. I hate computers anyways. the newer you go the more of a PITA they are.

so I pull the original 360 (still here collecting dust, sitting in the same spot) and put this overhauled 360 in its place with those brand new out of the box EQ heads on it. Fired right up, ran excellent/ not even a lifter tick when it 1st fired/ everything seemed great. I reused the original cam, but brand new OEM roller lifters. Warmed it up good a couple of times in the garage, set distributor SYNC with a scanner, felt good about it.
The 3rd night, I decided it was time for maiden voyage. I took off, and right off the bat I tried and failed to get the thing to achieve 60MPH. Built up gradual, was acting like it was starving for fuel. Went 2 miles, got it up to maybe 50 max, (all it would do) slowed down, left turn, it stalled. Started right up. Went a mile, tried another left, died again in middle of turn. Would not restart. had gone a total of 3-1/2 miles at this point.
Called my son for his truck + a tow strap, and while waiting the whole truck was glowing underneath like red neon. the whole exhaust was cherry red. In the end it melted down the new cat, and the front half of the new Magnaflow muffler is now gun barrel blue.
Got it home, got it running connected the scanner, and don't remember all prameters but one stuck out.... the injector "on time" which should be ~3 to 3.5 milliseconds at idle was running 17.some second mS. yes like 6 times what it should have been..... at this time having no clue where to go next, wondering if it was still the computer, or the injectors that were just rebuilt, flushed, and screens replaced, or what, I went to a U-pull and there was an 01 R/T Durango. Looked like a brand new rebuilt trans, computer was missing, it was a "sale weekend" so I got the whole wiring harness, and that fresh looking trans for a price I could not leave behind (always good to have a spare!)
I put that other whole engine harness on, and no change. Don't really remember seeing a problem with the original one, but grasping at straws at the time...

The kicker was going to drop the break in oil out and do the 1st oil change on it, with about 3 hours'' (max) run time. It came out a silver slurry, more silver in the mix it seemed than oil. It needed to come back out.

In the meantime I parked it, forgot about it. that was Nov. of 2016. The wife absolutely loved that Durango and she has been bugging me since to get back on it---- but I was pissed at it and decided I dint feel like screwing with it no more.... I needed to cool down and quit seeing RED. go at it with a clear mind. Besides I had 2 Dakotas, I pointed at the '96, 4wd one and said "Drive it"....

well about 6 weeks ago, the 92 Dakota that I have used as my faithful daily driver for the past 3+ years, puked the trans at 226K, instantaneously with absolutely no warning, and we were down a vehicle. Oh $#!t.. and I drive 70 miles a day.

I pulled the pan and there were large chunks (no friction either), looks like a planetary or sun shell exploded. I had rebuilt this trans (basic friction and steels and seals) at 203K. and it had been absolutely fine. Was perfect "the morning of" dying on the way to work, and again at lunch. Went to leave work, and it crapped out on me 3 miles away from the shop. called my son with the trailer, to bring me home.

Well, I got "talked out of" fixing that trans again, and went out and bought (ugh) a '99, 3.9 Dakota. I miss the 2 extra cylinders...…. and decided I had to $#!t or get off the pot with the Durango. I saved the 318 from the 92 "because I know where it has been" and knew that it is still a solid engine, planning to stab that in the Durango so we could again drive it, while I pull the rebuilt engine for a look see..... well I found a (nother) 136K mile 360 on CL (more than 100K less, than what is on the Durango's body!) for a better than good price. this time, no rebuild.
the plan was to regasket this (2nd) CL 360 and drop it in. Head off any leaks before it was confined in an engine bay, preventive maintenance sort of things...
but there was 1 thing... I had that brand new set of EQ heads sitting on that engine that had gone bad on me, sitting in the Durango engine bay, hey, I WANT my $700 new heads on this engine! I pulled the CL engine down to its short block anyways, so I might as well get some good out of that $700 that I'd spent on those things (a small small percentage of what I have in this turd)
but guess what.... I go to pull the heads off, while that engine is still in place.... WHAT!? #4 exhaust pushrod bent... bad. pulled the valve covers.... #4 exhaust valve stuck wide open. This thing has sat, all this time untouched, to this point I haven't turned the crank a bit from when I pushed it into that side of the garage. W T F!?

so I pulled the EQ's, and also got a set of stock original heads out of the shed that I have here, a set of heads that is "guaranteed" to be good, off of a buddy's 200k mile 360 that has had synthetic oil from day 1, whose owner removed only because he wanted to build a stroker and wanted aluminum heads..... and these were now "in his way"..... I also still have the ones here that came from the (2nd) CL engine as well.....
I took the EQs, and the set of heads from the shed (just in case) out to a machine shop that I have worked with several times in the past.....

I got to the machine shop and the guy recognized them as EQ Mopar magnum heads before I even had a chance to say a word. I carried in the 1st, he went out and got the other one....
He said " Let me guess... You bought these fully assembled EQ heads, bolted them on your engine and the valves are sticking".... He was dead nuts 100% spot on....
As it turns out he had a set do the same. He told me he built up a 318 for some kid with a 60s Dart, and thought this would be ideal.... save machine work, time, and not much more than what it would have cost to go thru the original heads from that engine. "No brainer" well in his case he had this customer's 318 on the Dyno (I didn't even know they had a Dyno) and during the 2000 RPM cam break in, the set of these same heads that he had bought for his customer had done the same thing.... said it ruined a piston, ruined the new cam, and then some.....

So now I am REALLY confused.... did the sticky valves (and now bent/ stuck open #4 exhaust) cause the clogged cat and wide open injectors somehow? OR did the fuel problem cause the valve issue?
I have let this thing sit for most of 3 years (and out of 3 winters, 2 of which very bad, the only "good" part of this mess) and am determined to solve this issue. I have to get a mechanically "sound" engine back in there to eliminate that part of the issue, down the road I have some shorty headers, 1.7 roller rockers to put on, and then (guys on another Dodge forum that I am actually an admin on are twisting my arm) maybe a computer tune. I'm ready to put an Edelbrock 4bbl and Mopar "orange box" on this thing. I have to get it going and get some miles from it, the only way I am gonna get any of my moneys worth out of it.
being as how the wife likes it so much (or "did) I don't think that will be an issue.
When we were regularly driving this Durango, we did pull trailers with it occasionally.... nothing huge, the biggest load was a Wrangler on a borrowed trailer down, and a 80s Bronco II back, 600-ish mile round trip... and I'd have appreciated a bit more grunt.... usually a 6-1/2'X13' with a lawn tractor or 2 on it, sometimes a '78 Apache popup camper.
When hauling the mowers or the popup, the Durango always handled "like it wasn't even there" these are the most typical loads towed, and only a handful of times a year at that...…

In all of this I almost went and bought a 2018 Dodge 1500, Hemi, Tradesman, reg cab 8' bed) except for 1) I cant find any such truck that is some other color besides white and 2) After I bought my 97 Wrangler back in Y2K, I said "never again/ won't ever have a 5 yr car loan again..... well they wanted to string me out for 7 years..... If I won't do 5 years again I sure in He11 won't do a 7 year car loan... NO way no how....and I won't buy a 4 door stupidly short bed equipped truck, either. like 98% of all new trucks have these days.
and the kicker... I had talked to my bank, told them what I was looking to do and where it was being bought from, and was told that "they work with that dealer often, they are on the "preferred" list" but every time they came back with a "HEY... I got you x.xx% and your payment down to $YYYYY, when I would ask "who is that thru/whats the rate, they had not yet answered me with the rate that my bank offered me, nor had they attempted to get me financed thru where I asked them too..... this was a Friday nite, end of month, all kinds of "special" BS for "end of month" that wouldnt be offered the next day, and all day Saturday they blew up my phone with repeated harassing texts trying to get me back in there to talk some more.... THAT was the last straw and final deciding factor that a year old truck with 4k miles on the clock WASN'T for me. Instead I bought a 99 club cab Dakota, 2wd with 105K miles "old man owned" and came with a pile of maintenance receipts.... the kicker? "the wife liked it".... I really want a full size 1/2 or 3/4 ton again.
I had that '99 for 10 days, and guess what... hit a deer with it.... so I was without a truck for the same amount of time as I would have been, if I had fixed the 92 trans// and spent the same money fixing this one from the deer strike, as it would have cost me to fix the trans on the 92..... should have done that. so I got to drive the 78 Fury daily for that 2 weeks, 70 miles every day.... that doggy, still lean burn equipped 318, didn't miss a beat. it still loves the highway. 2.71 gears, 904, and all

so, if you made it thru to this point, can you PLEASE offer me some suggestions and insight on this Durango situation? Chicken or egg? Fuel system/computer issue vs sticky valves. This is 1st car/truck engine I have ever experienced valves sticking with, in my life. is there still life left at Mopar Style? I have never ever had this many problems in all of the vehicles I have owned over the years/ let alone all of this on ONE vehicle.... I am not going to be defeated

Wanted (really "needed") truck wiring harness

Posted by: | Comments Comments Off on Wanted (really "needed") truck wiring harness
looking for engine comp wiring harness from an 88 360 4 barrel truck or RC. Needs to have been from an auto/A/C truck. From the bulkhead out. NOT from a fuel inj. truck. That is what we are getting away from, the 88-92 TBI is the absolute pits/ would rather deal with Lean burn vs TBI.... We have a Freshly built, 360 4 bbl engine, mechanical fuel pump, and carb'd truck gas tank already in place.
Harness from an 87 MIGHT work, not 100% positive, I know the bulkhead connectors are the same on an 87 as this truck. I also know that one from an 85 WON'T work, unless we also swap out the under dash portion of the harness because of the terminals on the bulkhead being different.
Located in Illinois so, no, I can't come to the South or West and pull one myself..... need it complete, and priced with shipping. and (carefully) removed from truck. PM me here

this is for my son's 89 RC.

wiper issues

Posted by: | Comments Comments Off on wiper issues
haven't seen anything on late B wiper issues in a while, I did go back 4 pages and was back several years of posts on the forum in Late-B's so I figure what may be further back may be outdated as far as parts availability and such anyways.
on my 78 Fury I replaced the main drive link (whole thing-- metal and plastic) probably 8 or 9 years ago. and I do not drive it much (definitely not enough) as far as I know the chrome molding at the bottom of the windshield has never been off the car since it left the factory. but if I haven't "just" had the wipers running sometimes I gotta "help" them get past that trim when I 1st use them... nothing appears to be amiss there. but the real issue is the other link... the one between driver and passenger wiper pivot. one end just doesn't want to stay on, I replaced the button on that end with crappy Dorman, the original one on the other end still pops on way harder than the Dorman ones. Last time I replaced that one that isn't as stiff with another Dorman button it lasted a week and about 3 tries of the wipers... and then I have drivers wiper only... in those 3 times, it didn't seem to have its normal issue of sticking on the lower trim when 1st started, but it was while they were wiping that I lost another of those Dorman white buttons in that link. Are the originals (hopefully NOT repackaged Dorman POS' with a Mopar sticker) still able to be bought? As I remember my 92 and 93 Dakotas took what looked to be the same piece, have not needed to look at the wipers on the 96 yet.... but taht's 18 years newer so hopefully there's hope that I can still get those push in buttons right from Mopar.... Anyone know?

radiator question

Posted by: | Comments Comments Off on radiator question
I need a radiator for my 78 Fury. was hoping someone had a copper/brass modine or something like that around but most everyone wants to sell me a Toyota looking POS plastic tank/aluminum core thing...
I found a couple places online that offer a 100% aluminum, tanks and all one for it. Radiator Express has a 100% aluminum TIG welded 2 row "heavy duty" one for what seems a good price, salesman says made in USA and lifetime warranty.
My question is this/ I am leaning towards that solid aluminum one, certainly do not want the plastic tanked POS even though it is $100 less.... but now I am adding in another different metal to the mix. The dash ahs never been out so the heater core is still the original copper/brass one. With a cast iron block, heads and intake, copper and brass in the heater core and now throwing an aluminum radiator into the mix. Will I have to worry about a reaction between all these different metals and something getting "eaten" away, like boats whose steel hull gets eaten away (that's why they attach hunks of zinc on them so the zinc gets eaten rather than the steel) they offer some kind of zinc petcock for an additional $18.95 that they claim to "sell the Hell out of" but made no mention of it being mandatory for the warranty to be good, etc... Any thoughts?

pistons difference between LA and Magnum 360?

Posted by: | Comments Comments Off on pistons difference between LA and Magnum 360?
I am building a fresh 360 Magnum for my wife's Durango, as its original one is showing its age at 257,000 miles and counting.
I went out onto Craigslist and found another engine to build, as we are still driving the Durango.
I just heard back from the machine shop, confirmation of over and undersizes of parts that I gotta get for it. std bearings and +0.030 pistons and rings.
On the pistons; I am wanting to go with the Sealed power hypereuctic coated pistons, have used that series of pistons on a few builds now. but pistons for a '93-03 Magnum 360 are like $$2x what comparable 360-LA engine pistons cost.
LA 318 and Magnum 318 pistons are almost the same price as each other, what gives with the 360?

What would keep me from using LA 360 pistons and rings in a Magnum block>
I mean you can put Magnum heads on an LA block, I've done it a couple times. so it isn't a valve>piston issue.
I built a 360 for my son's Ramcharger and used the Sealed Power Hypers with 4 valve reliefs. Same 0.030 over. Why couldn't I use those same pistons in this engine? $130/set with rings vs $230/set with rings, for the "Magnum engine" pistons. Listed at same CR, same brand, same material, just a slightly different head configuration.
