Took the pistons out today. All measure right at 4.2776". Meaning I wanted a final bore of 4.282. I chose to make it a a little on the loose side as I plan on spraying some nitrous with this build.
Forged SRP Pistons. 18cc dome will create a 10.2:1 CR with my 119cc heads. Uses 1/16, 1/16, 3/16 Rings.

Instead of the traditional bore and hone. We decided to hone it over. We have diamond stones in our hones and create less/zero taper as compared to a true bore/hone, as the hone is almost fully computer controlled.
