500 vs 512 from 400ci

Wow that's going to a ripper for sure, at that rpm I'd keep the stroke shorter but that's because I want an expensive engine to last. The others will do it with quality parts for sure.
My current setup sees 7300 every time I take the car out. I miss this a lot. This winter is killing me. They promised global warming and I’m freezing my *** off ;-)
