Since some of the scenario challenges require race motors shouldn’t we have race gas (100 AKI)?
I agree… you can buy 103 Octane fuel additive that will convert 93 or lower gasoline into 103 Octane… 103 should be a fuel aswell, I run it in my Impala currently and it stops pinging and many issues cause of gasoline being different today.
was your impala meant to run on leaded fuel? If so you need new cylinder heads that are hardened and you can run on unleaded just fine. You can either have the work done, or since the motor is likely an SBC just grab some more modern heads.
Yeah i know this… Im actually swapping the motor out itself to preserve it due to its nature of being a real L79 Worth 10k.
