Old school 3.58 stroke 340 mains crank. std. 2.5 mains and -.020 rods. Cast 360 casting with a big X on it (hey, It'll match my X heads for sale!) quick math tells you that this will raise your piston .135 in the bore with everything stock, so now your lo-po 8:1 318 kerosene burner @.070 in the hole will be a +.065 pop up. Mate it with a .040 head gasket and you'll have some serious squeeze even with big 360 heads....$150. cheaper than turning your tired old crank down! Gunk on bearings is 20 year old grease, good bearing
