Differences between 1972 2wd 350 and 4x4 350
 

I will be returning my 72' 3/4 4x4 Suburban engine compartment back to stock. I found a complete 1972 2wd truck 350 to swap in but, was curious what is different between 2wd and 4wd? I know the radiator hose pipe is and that is about it as far as my knowledge on the subject goes. Anything else different on the 4wd 350 engine compartments? Thanks in advance.

If it has A/C the vacuum can mounted to the AC box has an offset bracket on the 4x4. I'm guessing it gives more clearance to the valve cover because the motor is set back?

Dipstick and tube is longer and bends forward on 4wd

Engine mounts?

not sure about '72 but, my '68C10 uses front motor mount location and my '68 K20 used rear motor mount location in order for the oil pan to clear the front axle.

Would this have been ‘72 only?

Fan shroud is different for 4x4.

Throttle cable is shorter on 4x4 ('71-72).

I don't know if/when it might have changed year wise, but the AC vacuum canister on the 4X4's was metal whereas the 2WD were plastic. Won't apply to your non AC truck obviously.

Exhaust manifolds are also different. On 4x4 they go straight down, and on 2wd they angle back.
