65 BARRACUDA HEADERS?

a friend of mine now passed, art Rasmussen made a set for me about 40 yrs ago. I think i bought a set for a 2nd Gen barracuda, and then we picked up half dozen mandrel u bends, and a case of beer, and we spent a night at Dennis Smythe's shop and we modded them to fit my 64 dart 340 4spd. They worked pretty good. The best I ever ran was 13.0''s @ 104 on JC Penney 7" wide cheater slicks. No PS, manual DB.
