You can use your 302s flywheel as long as it is original to the truck, they changed the balance in the 80s and the newer ones won't work. Sorry 302 manifolds will not fit, bolt pattern is different and the ports are about half the size. What years is this motor? Are you sure it is a C and not an M or a W?

I will find out all the info as soon as i can......another question what would be a easyier swap 351w or 351c?

 

The Windsor is easier. They're much more similar to the 302. The exhaust manifolds interchange between the 302 and the 351W. But you still need new brackets.

 

You will only run into big trouble if you have an M. The only difference between the W and the C swap will be the exhaust.

K just wondering i appreciate all the info you guys are giving me really is interesting and helpful!!!!!

 

I have a 351C in my 79 2WD and I used car exhaust manifolds.It is a really easy swap,bolts up to the 302 mounts,bellhousing and flywheel.
