thanks this engine has holley carb& intake dartheads wild cam also bored&stroked& balanced what should timing be
Sounds to me like your best bet would be to power time it. I would start at maybe 4 to 6 degrees with no vacuum advance and then let it warm up good and start advancing it just until you get a border line ping out of it when accelerating hard.. Then back it up about 2 degrees, this should give you optimum performance. Only thing to be careful of is that it still cranks ok when hot. If not you will need to retard it a little more. But that is the best way to get maximum efficiency out of it. Thanks
