I have a 344 kit I bought from esr +4 crank 330 esr cylinder. piston is above the cylinder about 1mil. and I have newer esr cool head And dome. It’s set up for race gas but I want to drop compression. I have tried to measure dome size 3different ways and I come up with 37cc?? It can’t be that big can it?? Lol

I’ve never had luck measuring them either. Just do a compression test. I think over 190 psi you need race gas. ESR dome should say by plug hole pump or race.
