I was looking into the different piston configurations available for a 292 and had a few questions. It appears the face of the stock pistons have a 30 cc depression that covers most of the piston face and I read where it offers a compression ratio of 8:1. Then the lower pistons that have a 15cc depression that will provide a 9:1 ratio. I was thinking of going with the lower pistons but then today I found someone selling flat top pistons at .040. I was wondering if anyone was familiar with flat tops for a 292. Any idea what sort of compression it would have or if there are clearance issues? I am not looking for anything to take to the strip but would like an engine with definitely more get up and go than normal.
Thanks!
