View Full Version : Looking for information on 455 Rebuild to get 400HP

I read an article years ago about a 455 rebuild using 6X heads, a cam change and I believe a piston change, that yielded almost 400 hp. Of course now that I want to do it, I can't find the article. Any help would be appreciated. This was using a 73 engine.
