I'm not a mechanic but I'll learn.

Essentially with the V8 swap you will keep the body and ditch everything else lol.

If you dont have an 8.75 to start with. Figure on spending minumum $1,200 to build one up. I did one for my 67. Will be going xploder sport trak 8.8 on my sons 69 barracuda though. I cant argue w $200 for BBP, discs, 3.73s, and a locker VS $1,200 or more and still being drums.
