Need advice on Holley carb.

I can tell you that .057 IAB is way too small unless the IFR is about .020 or something like that.

I’ve never seen a combo that wanted that small of a IAB. The MAB looks small too, but I have no idea what emulsion is in there.

4.10 gears will take an 8.5 power valve, and probably a 10.5 but you have to check vacuum to know that.
