Mike - unless you are well experienced in the setting up of Holley carbs (and I don't personally fall into that category I hasten to add), it would be very much worth your while to get the carb set up on a chassis dyno by an expert.

Will save you much time, possibly many $$'s, and stop you getting into a lean detonation........holed piston situation.
