what about all the aftermarket heads that have no crossover? my 526 has RPM heads, and a holley 1000cfm hp carb, with no choke housing. no issues with cold start/warm up.
Yes what about that?
Supercuda: Norway yes!
Hoozie: Running manifold vacuum - not ported. No vacuum reading in drive as it is a manual. Idles at 12hg vacuum. Not sure at which vacuum the advance kicks in but should be well under 12 hg as it is all in at idle.
