LT80 Moded cylinder Compression

All you guys running Moore LT80 engines, what kind of cylinder pressure are you at? We just burnt a hole in the piston this past weekend. I just got it back together and am at 180 cylinder pressure. I was running 93 octane. I talked to Jack and he said we may need to run Race fule in it. What are you guys running? a 50/50 mix of race and pump or straight race fuel? Also What octain race fuel you mixing or using?

we ran pump gas in our jack moore motor no problems we only had 160 comp tho not sure why yours is higher .sure you don't have a leak some were sucking in air we never burned a piston allways wiped the rings from water tho.hope this helps
