If I put an 8:71 GMC on it, is it feasible to just use octane boost instead of race gas to keep it from pinging, etc? And if so, how much would I need? The local gas is 91 octane. Also, from my understanding a large cam bleeds off compression so why not just put in a huge cam to lower the compression??? Thanks Bill
Bill,what pistons are you running?
Is this engine 4.155 bore x 3.80 stroke?
