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
