Talk to Mike at MLR (and buy the parts from him), He will maximize your build for your weight, converter, driving style and a dozen other factors you might not have thought of. Did a great job for me. Hes a sponsoring vendor here too.
I had tried to talk to mike several times but for some reason I could not get the shop to answer the phone. Since this is for my sun to drive and is just a cruiser, I went with the Hughes whiplash cam meant for low compression engines, double roller timing chain, matched springs and lifters, the X heads and an Eddy air gap manifold. Going to save some on the funds so I can Finnish building my 367 old school stroker.
