    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?
    That's RACIN!
