Keeping in mind that I can test drive the car maybe to 30 mph for 30 minutes in its current condition I don't know what that will show me. You mention 4 jet size differential between primaries and secondary's, the larger in the secondary's, is that for a Holley? As I stated, The FSM calls for 89's in the mains and 73's in the secondary's but that is a Carter AFB, different engineering characteristics I guess. I need a baseline for a Holley.
BTW, thanks to all for the advice, I appreciate it!
