428 initial timing optimal??

By Tim - 04/16/2003 1:24:46 AM; IP 24.64.223.204

Hi guys just broke in my engine ( cam ) the other day and am now about to tweak it a little.
Carb set up and timing

I have set the initial to 14 deg and the advance stop on my MSD billet is the blue advance stop bushing giving 21 deg (springs 1 Blue and 1 Light silver)
looking at 35 total in b4 3000 rpm

Q) How do I go about determining what is really the best or optimal initial timing and also what determines what the idle rpm will be??
I have the edelbrock RPM package less the carb went for a Holley 850

Tim

Sorry to say, but both types of floats have their problems. [n/m] -- Mr F, 04/23/2006
