which fuel? I have been having some arguments about what type of fuel I should be running. I am running a 383 stroker ls1 with an aluminum block. It has 11.3:1 compression, with untouched stock heads from a 98 TA. All the LS1 guys I know say I'm fine with 93 octane pump gas. I have always been taught and my machinist agrees that I should run a minimum of 105 octane with that much compression. I am about to get it tuned so any advise would be greatly appreciated.
