Super Comp Headers
I believe that I read a technical article somewhere recently (probably online) about installing TTI headers on a 70's era Dart (or perhaps a Duster)...... I don't remember exactly where I saw the article, but it was a very positive write-up.
If you haven't ever looked at TTI's website (Tube Technologies, Inc.), check it out. Even though I haven't yet "bit the bullet" and ordered a set for my '65 Barracuda, more and more I'm thinking that TTI is the way to go - and the way I'm going to go.
