The type of heads you have will be a major determining factor on timing. Chevy's new crate engines with vortec and fast burn heads like 32* - 34* total (w/o vacuum) where as older design heads can use 36* and even a bit more. I found my Eddy RPM's sweet spot at 35*. This is something you are going to have to experiment with to get the best performance. If you have conventional heads, start with 36* total and work up/down from there. IMHO
