Re: tuning a 383
When I built my 11:1 cr 350, I had to limit my centrifugal advance otherwise I experienced severe pinging from 3000 rpm and up when using low octane fuel.

Re: tuning a 383
What GM crate did you get? ZZ383 or HT383? What kinda gas mileage are you getting? I know you're the one with the questions but I'm curious about your motor.
