Holley, #4412 --- you can change jets and remove choke horns. Don't mess with anything else..........

i was kinda wondering that too... i've seen alot of carbs out there that look just like a holley and are the same cfm... im sure theres a reason for us having to use only the Holley, but im not sure what that is...

It can be re worked. 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.

You can use any 4412 Holley, but it must pass the go-no-go guages.

Most if not all carb builders know about the guages

The guage checks are pretty thorough

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.........
