69 Dart 5.7 "Butters" Build

Sweet deal. I would jump to a 6.4 too if the right deal came along.

Which manifolds are you selling? I have headers so not looking for any, just want to make sure you don't think the 6.4 manifolds will fit.
I'll be selling all maniifolds I have lol.. Durango and SRT. I don't see any way around doing headers
