Stock cast iron 452 with stock valves and bowl area just cleaned up. The pistons fit in like a glove.
Silv-O-Lite Cast Pistons 1276-040 they didn't need any modification they fit right in. The customer was on a budget and was able to find them on the extreme cheap since the previous guy was throwing them out. I would suggest using a 383 steel crank because it makes balancing easier. Basically it's like a bigger 383.Let me tell you he was happy with it. He surpassed the 440 hp and reved very well. Yes you can get light pistons and make more HP but for what he paid he was like I said happy. Glad I can help don't hesitate if you have more ???
