How much compression on the aforementioned small cam 870hp? I am seeing guys run the e85 and being consistent. I can't afford 8 dollars a gallon for race fuel. I will have to scrape to get one of these high dollar hi-po engines to be honest, so I realize you save money doing it right the first time and not doing it over, the second time.
