ok first the cam would need changing because it meant for a car. now for the really sucky part. your truck never came with that motor so finding the towers that bolt to the frame are not existent. i tried this with my 73 ford highboy a few years back and got rid of the 351w because of it and went to a 390 which in my mind is way better then the 351m/400 anyday. there is also more aftermarket for the 390 as well.

It would be a good motor for your truck, should have decent heads on it, but yeah, you might want to change the cam. As for mounting it in your truck, 302/351W/351M/400 towers are all the same, you just need a set of truck 302 motor mounts. What engine is in the truck now? You will probably need to change the bellhousing and clutch on the tranny to complete the swap.

I have a 351W in my 76 f-150 4x4 it was a pretty easy swap. All you need is 351m/400 motor mount perches (ford never put a 302 in a 4x4 in the 70's) , The hole will need enlarged slightly but that is all. Next you need a bellhousing from a 300 six and you will be readdy to roll.

by the way where in PA are you located?
if you are close to somerset you are welcome to stop buy and take a look at my install and go for a ride to see if you like the power of a windsor.
my truck is similar to yours. 3:50 gears and an np 435 4 speed
