The Edelbrock Performer Series 800 CFM manual choke carburetor (1412) is a precision-tuned square-bore unit that uses metering rods, resists backfire issues, and retains its calibration once tuned. The two-piece aluminum body resists warping and is compatible with common blended fuels. In dyno testing on a small-block Chevy, the EPS 800 showed notable gains over a comparable Holley unit in both torque and horsepower.
