headers 440 dart

I used an old set of Proparts on my 71 Duster which was 440 w/4-speed. We had to modify the bellcrank, but other than that, they fit very well. However, as mentioned by abodyjoe, you have to dump a couple pipes into the fenderwell on the driver side and one on the passenger side. That car was already cut for fenderwell headers so it was no big deal to me. If I would have done the fenderwell cutting, I would have cut holes just a little bigger than the pipes, like I did on the Barracuda, so it wouldn't look quite so bad.
