The Edelbrock Carburetor EPS 800 CFM Electric Choke is designed and calibrated for maximum street performance with most Performer RPM, RPM Air-Gap and Torker II manifolds and with Performer manifolds on large cubic-inch engines. It features two piece, all-aluminum construction for cooler fuel and less warpage. Tests proved that the EPS 800 carburetor outperformed a Holley 3310 750 CFM carburetor out-of-the-box by 26 ft./pounds of torque and 22 horsepower on a small-block Chevy engine equipped with performer RPM components. There are no gaskets below the fuel level for easy adjustments without removing the carburetor. The EPS 800 has the same superior features as the rest of the Performer Series line such as out-of-the-box performance and 2-piece design. It features a high capacity accelerator pump and an improved primary and secondary cluster design. There are no plastic parts to break and no power valves to blow out. The metering rods can be changed within seconds without carburetor removal. It comes with 113 primary metering jets, 101 secondary metering jets and 0. 071 x 0. 047 metering rods.
