So I have a numbers matching 72 340 duster... It is early enough 72 the motor came with the big valve j heads however I believe it's still had the 8:5/1 compression ratio... My intention, I'm going to keep all of my numbers matching parts however this motor will be built to the spec of a 1970 340 4 speed car... I am looking for a set of exits that aren't into terrible shape, if anyone could help me out with that I would greatly appreciate it!
