Compression

Are those flat top pistons and do they have cc rating? I'll do the calcs tomorrow, my district manager has been in town all week and he's been piling on the work. I need to get some sleep.

Hi ramcharger,
They are flat tops semi-symettrical, I believe 8 CC, not sure box is at machine shop. The machine shop has run the #;s, and 11.5:1 is what were getting, I can flycut the pistons to 0 deck height and get it down to 11.2:1 or go a little thicker on the head gasket and drop it alittle more, but I want to know for what I drive it is 11.5:1 too much? Or is it not worth the trouble with possible detonation.
Thanks for all and anymore comments.
T.J.
