how true is it that with a big cam like webb4, x4, or 5050, a 12:1 piston is pump gas safe at say 1000-2000ft. i have seen this a lot of places and am a little skeptical, but since i'm not a motor expert, just i thought i'd ask some people a little more knowledgable than me. and searching this out has resulted in many hrs of reading useless threads. :lol:
