need help from knowledgeable Chevy Guy
Hi,
Building a dirt track car, the rule book says we have to run a stock production replacement piston. Now I think I can get away with a 2 valve relief flat top, but did a 350 ever come out with a dome from the factory? If so what?

Here are the links to the tracks I am looking at. Look at the rules and let me know what you guys think.

Look at the rules for pure street and street stock at both tracks. The rules are very similar. tires and vacuum are the only real difference.
