65 Valiant

I think so, since it require that unique valance cut-out. Search here and you will find many posts. One place makes/made repro HiPo exhausts. The AllPar site has more info and photos. A member here from Sweden is the expert on the 65 HiPo stuff. You can find many posts.

Congrats you lucky devil. The rust doesn't look bad to guys back East, though worse than most AZ/CA cars. Hopefully, it will clean up. I understand there is nothing to distinguish the engine blocks or heads, just the pistons, finned valve covers, and 4 bbl iron intake were special, so if you get any 65 block and those parts, you can put it back to "correct and valid".
