We ran a gauge legal Willy's 4412 that was an awesome carb. It would respond to 1 jet size changes and never gave us a bit of trouble. When we got out of the class, we sold it to a guy in Illinois. They are about $550-$600.

Here ya go -- right from the rule book -----

CARBURETOR:
1. One (1) Holley 500 CFM. Two barrel carburetor (no. 4412 only).
2. May change jetting.
3. No after market performance meter blocks, subject to tech.
4. 1 11/16” throttle bore, 1 3/8” main venturi.
5. Two- (2) throttle springs mandatory.
6. May remove choke tower.
7. Carburetor must pass all go- no go gauges.

Be carefull with the re-worked carbs, line #3 could get ya in trouble.........
