Ok, so after some debating in regards to what combo to run 376(with ls3 top end) or 370(with cathedral heads) for my lq9 block. I have decided to go with boring the block .030 over for a 370 and going with Prc 2.5 5.3 heads and either an ms3 cam or tsp 233/239 cam with a goal of 450-470 rwhp n/a. My question is what type and style of piston can I use to keep my Compression any where btw 10.8 or 11.2, as I would still like to run 92-93 octane?

Why aren't you using ls3 heads on the 370?

With my 370 build, I'm using wiseco flat tops with ls3 heads, and a custom cam. You can use 93 octane and still run 11.5 to 12 compression. It's all in the tune?

Well, it is going to be cheaper and I can still attain my goal

I really would like to keep my compression close to stock.
