"El Mongrel" '65 Formula S Restomod

He wants it to look some what stock remeber:glasses8: Nice build by the way:rock: How much do you think the headers improved over the original 273 manifolds?

Thanks. The stock system was 1 7/8" compression bent single exhaust. The cast manifolds were marginal for a small V8 especially the drivers side. It went from a round log and morphed into a flat rectangle that curved around the steering column then back to a round flange. I think I could fart harder than that thing could flow.
