After a 40 year hiatus I've bought some flatheads for a '47 PU project, I will probably use the '52 Merc, so what I'm looking for is some advice to build a street motor using some modern ideas. I figure what's happened the 4 decades that I was involved with SBC's there must have been some advances that improve reliability and usefulness. Previously (early 60"s) it was mill the heads and dual exhaust and an intake swap if you could find one. I know Offy still makes intakes, are they any better than the old ones? how about the cams, heads etc.???
