Fuel detonating in intake?

My son has a 66 Polara with a 383. We don’t have a temp gauge hooked up, and my son is fixated upon the car overheating. He said the car overheated tonight, and that the fuel was detonating/burning in the intake and never making it into the cylinder. This sounds totally crazy to me, but he is 16 and he knows everything....just ask him

:rofl:

does this sound credible or crazy to all of you?
