Definitely didn’t have any ring seal issues. The new piston has a tighter quench cause the dome is much smaller and flatter. That and a smaller oiling ring, plus little compression and .100 more stroke. I don’t expect to find a ton of HP. But I would certainly expect it to make some more power. How much? We will find out.Unless the original block had ring seal issues it will probably run about the same, maybe a hair quicker if the additional stroke helps the 60'.
