750 CFM - 4150 - Mechanical Secondaries - Shiny - Gasoline
These carburetors that are intended for use with superchargers, and have a unique capability that allows their power valves to reference the intake manifold vacuum below the supercharger. This allows the power valve to operate as it should, based off intake manifold vacuum. A power valve provides further enrichment to the main metering system under load (low vacuum) conditions. Without this external referencing, the power valve would be "reading" the supercharger vacuum, which has no bearing on the engine load.

- Tumble polished shiny finish for good looks
- Boost referenced power valve for proper enrichment under acceleration
- 100% wet-flow tested by Holley technicians to assure it arrives ready to run!
- Small block Chevrolet 1x4, 170 series blower calibration
- Manual (Cable driven, hand operated) choke for precise cold start control
- Dual accelerator pumps for addition fuel under initial acceleration
- Dual feed fuel inlets for constant high volume fuel delivery
- Mechanical Secondaries for perfect off the line launches
- 4 corner idle allows you to precisely control your idle system
- Intended for lightweight vehicles w/ manual trans or automatics with high stall & low gearing
Information:
This model of carburetor has the square bore flange bolt pattern. It can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with 5 3/16" x 5 5/8" bolt pattern. If you have a spreadbore style intake manifold, you will need an adapter to install this carburetor. Similar to the Mr. Gasket #1932.Application Summary:
