Easy 30-minute swap-in, swap-out installation utilizing existing metering blocks, fuel bowls, and base plate. Involves only 14 screws. Instructions, high performance jet kit, and non-stick gaskets included.

  • High-performance down-leg boosters
  • Get maximum air flow with no air horn, choke tower, or choke control

Do they make a Holley Carburetor Main Body for 750 CFM Alcohol Carb dual feed double pumper. We run a modified open wheel on dirt and the threads holding the back float bowls have pulled out and would like to replace the main body instead of buying a new carb.

Sorry we do not offer a main body only for a Methanol carburetor. We do offer a fuel bowl screw thread repair kit which is part number 425262. That kit will install a thread insert into your main body so that you do not have to replace it.

No this is not legal for use in IMCA Sportmod. You must use a Holley brand main body such as part number 425134300C or 425134300S.

Yes this carburetor is setup for a 4 corner idle. Ideally you will use a true 4 corner idle base plate along with it, or base plate 58667155 is an excellent addition which is a 4 corner idle.
