That's a nice car....and looks familiar! Was it there when I came by? B body headers will work with a few dings if you don't want to hack out the fenderwells. Look on Big Block
Dart.com and I think they give Hedman headers part numbers that will work. I believe I'm gonna do my 68 Roadrunner the same way. Make it safe, make it fast, Maybe wash it.....maybe not! I'm gettin too old to try and make all of em shiny!
