All the information in this topic seems really good for us. But I have noted that has no one answer about where you can get performance parts.
I don´t know where you live, but if you are in the US, you can find some of these parts in PES(Performance Engine Service) and in the Sissel´s site:
www.sissellsautomotive.com About the pistons, my opinion to you is to search in Ebay. If you will choose a 250, you can search for Chevy 307 V8 pistons too. Sometimes its easier to find some!
Good luck in your project!
