It should start just fine with low advance and the total should be in the 22 - 25 total degrees of advance range.

Bored&Stroked, Yes, it has 25* static advance and with RPM will hit 35* with the vacuum brake full on, bolt fully in. Keep in mind, the distributor thinks it is zero* at TDC, so I'm only getting 10* advance from the distributor.
TDC was determined two ways, with a dial indicator when the heads were off. After heads on, I did the double stop method with a big zip tie. Both TDC's agree by a degree or so. What should the base (static) timing be for an Isky 77-B cam? I can't find that anywhere.
Flatjack9, I'll see what I can do with the exhaust event plot. That may take me awhile.
Thanks guys
