Okay...I got my basic question about engine swaps answered...now I have a specific question. Has anyone ever swapped a 351C into a 67/68 fastback? Is it possible? I've heard you need to cut the shock towers some...are the shock towers bolted or welded on? What other modifications need to be made? What kind of transmission/exhaust manifolds/headers will work with this swap? Thanks!

You can fit a 351C into a 67/68. You can even fit a big block! It's the 65/66 that has problems with the C. It can be done with tower massaging!! Hope this helps!!

The front end on that 67 is basically the same as a 70.... The year a 351C came in a Mustang. Manifolds/Headers for a 1970 reportedly will fit a 67 with a 351C..... Everything else (motor mounts, flywheel, bell housing, clutch, etc.) will swap off a 289/302.

I did it in a coupe and a fastback. Just had to change exhaust.

Talk about a smokin' ride. With a two barrel I got clocked runnin' over 140. Yes, I was scared. Darn thing was bouncing all over the road. Nose was lifting and the rear was sliding back and forth. Passed everything but a gas station.

In the Fastback I had a three speed and I could smoke the tires thru all three. /forums/images/icons/smile.gif
