- Improves Off-idle Response
- Dramatic Increase In Torque
The Edelbrock "Performer" is an ideal performance replacement for Corvettes with stock small blocks with performance cams and/or headers. The "Performer" dramatically improves off idle response and low end torque and extends all they way to 5,500 RPM. The QuadraJet carburetor bolts directly to the "Performer" utilizing all stock brackets, fittings and cables. Rejetting of the carburetor or other modifications are not required because the manifold fits under all stock hoods. Gasket is not included. For 1963-68 327 engines, a provision for machining a oil fill tube hole is in the casting or use 1969 and later valve covers.
