I'm replacing the 302 in my model A hot rod with a y-block to make it more 'era correct'. I was planning to do a quick tear-down and rebuild of this old '57 292 that came in a parts truck I had. I researched the casting numbers and it turned out to have the desirable ECZ-G heads and block.



I'm thinking that it could be a 312... and that would be cool; but no way... it's a 57 f100 and the numbers show that it should be the correct engine.



I pulled the pan yesterday and son-of-a-gun.. ECZ on the caps, and a BIG ECZ on the front counter weight... nice. It is very clean inside and I know it has been rebuilt at least once because there are numbers stamped in the rods and caps. It has a double roller timing chain.



But one of the heads had this: (see attachment)



SO Now... what should I do with it? It's going in my hotrod and I'm running open headers. I want it to be reliable, and not overheat, so I'm not going too high on the compression. I will have hardened seats and SS valves installed. What is a good, lumpy cam?



Any suggestions?
