Quote: The point of deminished returns on a gas fired engine is aprox.16 to 1 after that you won't need spark plugs and can run diesal or veggie oil or weassel piss depending on what performance level you desire.
I have a 572 B1/MC 16.4-1, in Salt Lake at 6000 corrected runs 7.54@174 in a 1870# dragster. I run Sonoco Maximal. I'm guessing 7.20'2-7.30's in Las Vegas with good air at MATS.
