magnum 5.9 with aftermarket pistons

WHAT A WORM!!

I knew something wasnt jiving, thats why I posted those numbers. The 405p smogger pistons are NOT .170 in the hole, the are .107. I did misread.

That puts the smoggers at 8.75:1

That should put the KB pistons at .008 in the hole. With a .028 gasket thickness, that puts it at 11.3:1, with a .035 it comes out to 11.1

but I have been using 60 cc chambers. And from what I understand 62 is a more realistic number. With 62cc chambers, and a .040 compressed gasket it comes out to 10.75

I thought these keith black pistons were good street pistons. Am I off track?
