I have a 69 XR-7 that didn't have a engine or trans when I bought it. I was told that it came with a 315w and C-4 (I think). I can buy a 79 XR-7 with a 351 and ?? trans for $100. I know the 79 engine will have alot of emissions crap, and hopefully I can strip it all off. Will this engine and ?? trans work in my 69?? Thanks!
