It was originally thought that it was a 327... however 1958GMCNut ran some numbers found on the block and it came back as a 350... no big surprise... the "Turbo 350" tranny it was supposed to have when I bought it was discovered to be a Turbo 400 so they weren't sticklers for accuracy in their ebay listing... wink

I don't see myself staying with early chevy exhaust... as I said the old exhaust manifolds have hairline cracks and are dull and crappy looking (as cast iron is) and I'd like to dress it up a bit so it wilol definately be headers... which ones are the question which is why I posted this...

So it seems popular opinion is ceramic coated... I'm a bit shocked since I figured polished stainless or chrome would win out, but I have to pay attention to all the folks who have used 'em and if ceramic look best for a longer period of time I guess that's the direction I'll go...

Still a bit worried about clearances and would like to know what brand/model other guys with '37 body styles use to be sure they'll fit but at least I can narrow down the search a bit now... thanks to all who have responded! smile
