I have a 68 two wheel drive F100 that I installed a Crown Vic frontend under. Came original with a 240 six cylinder and I am installing a 302 with an AOD transmission. My screw up is the fact that I didn't take any measurements as far as engine placement. Is there anyone out there that has any measurements they could get me started with? Any diagrams, personal experiance, anything?? I'm at a stopping point now until I can get this figured out. Thanks in advance, Gary

 

You can put it anywhere it fits for the most part. Level the chassis and level the motor. A 302 will fit in there without too much hassle. Sorry I can't give you any real numbers. Mock up radiator/shroud and go from there.

 

I don't have the dimensions you're looking for but I think I can give you some hints on how to position your engine/trans.

I'm putting a 351W engine and 4R70W transmission (same external dimensions as the AOD, I think) in a '70 SB 2WD F100. Think your engine/transmission combo should be positioned the same as mine.

The 351W is positioned by the stock 302 frame stands. On the stock frames stands, the 351W valve covers clear the pinch weld on the fire wall by about 1/2". Edit: OOPS!! It is the driver side head that clears the fire wall by 'bout 1/2". Pinch weld is much higher than the valve covers. The air cleaner sits under the pinch weld about 1".

The crossmember for the 4R70W transmission mount positions the trans so it clears the trans tunnel by 1/2". That put the intake/carb surface very close to level (can't tell for sure because the truck isn't assembled completely).

Notice that the trans tunnel is offset about 1.5" (didn't measure it) to the passenger side. The stock frame stands give the engine about the same offset.

The radiator mounts on the stock core support are tilted back to match the engine backward tilt. You can get a good idea of the proper rearward tilt for the engine by getting the crank pulley or radiator fan parallel with the mounted radiator. The backward tilt of my 351W/4R70W matches the backward tilt of the radiator very well.

 

Use lots of blocks of wood, to stabilze the engine under a hoist, and install your driveshaft. That is what will decide your engine placement. You have at least a good inch or so +/- to be off. Try and keep the bottom of the block flat to the ground. Make your custom motor mounts and your all set.

 

With the engine on the stock engine stands, the drive shaft had to be shortened by this much.
