40 degrees initial!

Thanks AJ. I'm a night owl. ;) My carb is an AED 750 and they come with butterfly holes already drilled (nice feature I didn't realize when I bought it), so that's already covered. I would prefer to not have to mess with the IABs and IFRs if I can avoid it. The guys at AED told me unless I really know what I'm doing, that I shouldn't mess with them.

What a load of ****. Mess with them and start to see how that affects your cars performance. If it were mine i would rip that 750 off and put a stock holley 650 DP with stock calibration on it. You would probably find that the 650 would run better all round.
