I just bought a 76 F100 that someone did a total junk job of stuffing a 78 460 into. I've pulled the motor and after reseaching the vin# it originally came with a 360. Do I need special motor and tranny mounts to get the 460 back in properly? Maybe new drive shaft too?
Hi, you'll need new frame engine mounts or perches for sure, the tranny mount should be ok. Put the proper mounts in and then replace the engine and trans before getting another driveshaft, yours may be ok once the engine is in the proper mounts. The frame has 3 holes drilled for the trans mount so you can shift it back and forth about 4 inches, so that may have been moved too when the PO cobbled up the install. Have fun
