Hey guys, I have a 383 with old casting AFR 190cc heads and I believe I'm about 10.5:1 compression ratio. I'm running Comp Cams 280xfi cam and a megasquirt II fuel injection system which I am tuning.
I'm trying to tune in the cruise RPM's and I believe my current timing is way to low in those areas. What kind of advance should I have at those rpms? Somewhere in the 1500-2000 rpm range?
