All that is not exactly right Cab. There is an 8896, 8896-1 and 8896-2. All 3 have .88 jets, but the -1 and -2 come with a 55 power valve.

There is the 9375, 9375-1 and 9375-2. The original 9375 has .92 jets and no power valve. The -1 and -2 has .86 jets and no power valves.

There is no 8896-3 nor 9375-3. There are also no 8896 or 9375 Ultra. There is no series of HP Dominators. They are either standard Dominators or Ultra Dominators. The HP series is the standard flange race carb with no choke horn and the Ultra HP has billet blocks and base plate.

You know, I DO work for Holley
