Re: L78 Total advance
My cars won't run on the 93 pump stuff without a serious dose of race fuel or av gas. I think we run 36* total..16-18* initial...all in by 3,000rpm. Vac adv is hooked up to manifold vacuum.
I'm amazed you can use the pump stuff and not have pinging...did you ever calculate the compression ratio when the motor was apart? Those rect port heads are notorious for having bigger chambers than advertised. tom
