Instead of doing the header thing, I thought that I could use a set of hipo 340 exhaust manifolds on s 273,4 BBL, 10.5:1 motor that I am finishing up. I don't like the chassis headers and the fenderwells are not practical for the street. I'm hoping that the 2 1/2" exhaust system should be a breeze on a '66 Valiant. Anyone done this?
