Does anyone know of any suppliers of vintage style speed equipment to hop up a 1951 pontiac flathead 6, Ive googled around to no avail, any leads? Thanks
I imagine for that baby you're pretty much stuck with making it yourself. Even 'back in the day' I don't think there was much if anything made in the way of "speed parts" for that engine, at least not commercially, anyway. There's one guy here on the HAMB - "Ogbomb" in New Zealand that just made a very slick intake and exhaust set-up for his '38 Pontiac 6 and he might fabricate some similar stuff for others. He's got an ongoing thread on his project. Check it out.

You would have to get someone to cut you a header flange out of plate steel. or you will have to make one by hand. You could trace the manifold out on a piece of steel plate or flat bar and use at least some of the bolt holes as drill guides to drill the bolt holes. When you got it all welded up as a set of headers you would have to run the face of the flange across a belt sander to get it flat but that shouldn't be too difficult. You might check over on the Inliners forum http://www.inliners.org/ubbthreads/ubbthreads.php?ubb=cfrm The guys over there are used to having to build their own manifolds and headers and come up with some pretty interesting stuff.
A buddy of mines first car was a Pontiac straight 6 flathead. He put a tach on it. The valves floated at 3200 rpm.
