in the middle of all the mess my car is going thorugh. i was just wondering what kind of Power difference is there between flat pistons, and dished pistons.

rite now i have dished, if i were to change to flat will i notice a g0od power increase?
Thankz

11 or 12cc( can remenber the exact munber) difference in the chamber cc's. that's about close to one whole compression ratio. Swap your piston to flat top and put little bigger cam and you'll feel the difference. pull to about 7000rpm

about 18 horsepower i think, not sure this is what i have heard. I think my z might have flat tops, but I will see about that. I heard you can just open up the spark plug and if teh piston is at TDC you can slide a flat head screwdrive across it and feel the bumps, man i hope i have flat tops lol.
