For those of you that want to run an H-pipe, I found this interesting. This guy has a 70, 4 door Chevelle. He was given an H-pipe from a 2012 mustang. He tried it and the spacing of the headers is the same. It lined right up. Might be good info for someone who can get a deal on a mustang H-pipe to use on their chevelle. Just thought I'd post.
