Holley MDL 4150 750CFM D/P-Chromate Electric Choke

Holley has taken their two most beloved double pumper sizes and made them even better by adding electric chokes. You can now choose from the 650 and 750 CFM models, available in both classic zinc and a stunning polished finish.

When it comes to performance upgrades for your hot street car or race vehicle, Holley Double Pumper® carburetors are an excellent choice. These carburetors have become an American icon, known for their impressive performance. With roots in many factory muscle cars, they have powered countless vehicles across the finish line, making them perfect for everything from street cruising to quarter-mile racing.

Designed for lightweight vehicles, the Double Pumper works beautifully with manual transmissions or automatic setups featuring high stall and low rear-end gears. Available in a striking gold dichromate or a sleek tumble polished finish, these carburetors come equipped with dual accelerator pumps to provide that extra fuel during initial acceleration, mechanical secondaries for outstanding performance, and dual feed fuel inlets for a steady high-volume fuel supply. Plus, the electric choke makes it a breeze to control engine warm-up.

Don't settle for anything less than the best; Holley has been the go-to modular carburetor company for over a century and has powered every NASCAR champion since the 1960s!
