Engine questions

I have a 65' Mustang. What I am wondering is, will a 351 W or C fit in it? Or will I have to modify the front end.

If the car had a 302 previously, I would think it would be a bolt in project. The only difference may be a little more front end weight.

Would have been a 289 in '65. A 347 stroker would be an easy swap, not sure about the W & C fit vs the shock towers.

I've seen a Boss 351C swapped into an early Falcon, so I know it is possible (tight though).

Check out this:

Here is a good thread on a 351C swap into a '65 (some bickering between two guys that have done the swap, but still informative):
351 cleveland 65 mustang - MustangForums.com

In short, if you get the right headers and motor mounts, you will not have to dent the shock towers. I guess the "you need to push in the shock towers to make it fit" part used to be common knowledge, now disproven.

From what I gather, the 351W will probably be a little easier (cheaper to build too). Taller deck height aside, I don't think it has as tight of side-to-side header/shocktower clearance issues as a 351C.
