Go-Fast Goodies

Overall, the stock Corvette heads are good, but you're looking for more grunt out. Getting airflow through the heads is one of the keys to small-block performance. You could pull off the heads, strip them and send them to a machine shop, but what are the alternatives? Fortunately, there are plenty, ranging from replacing the entire head with a complete unit or installing a bare performance head with a trick valvetrain. A host of companies offer cylinder heads with bigger valve diameters, improved flow and machined combustion chambers.

Edelbrock's new Performer LT1 intake manifold is now available for 1992-1996 LT1 engines and is aimed squarely at the street performance crowd. Fifty-states emissions legal, the Performer has a unique runner design that delivers more air and fuel for more torque and better throttle response. Dyno testing has proven gains of 35 lb-ft of additional torque and 25 percent more horsepower than stock intakes.

For your L98 or LT1 Corvette, CNC Cylinder Heads offers heads with exclusive port designs machined using Winston Cup CNC technology to produce high efficiency and precise port contours. They deliver maximum airflow capacity and high velocity, resulting in great advances in mid-range torque and top end horsepower.

ACCEL's Street Ram Fuel Injection System for Chevy small-blocks was developed in conjunction with John Lingenfelter to provide dramatic horsepower and torque increases and still be compatible with the OEM computer. The system comes complete with wiring harness, fuel pump and everything else needed for a trouble-free bolt-on installation.

Performance fans can benefit from the advanced technology of electronic multi-point fuel injection with Edelbrock's Pro-Flow system. The Edelbrock/Weber system utilizes an intricate sequential firing speed/density system for instantaneous throttle response, increased horsepower, smoother engine operation and better fuel economy.

For owners of earlier Corvettes, Holley has a first-string lineup of digital fuel injection systems in its Pro-Jection retrofit kits for carbureted, non-computerized engines. A total of six systems are available in 650, 700 and 900 cfm four-barrel versions to accommodate horsepower ranges from 150 to 500.

Howell has an aftermarket fuel injection system specifically designed for refitting Corvettes originally equipped with carburetors to a TPI system. The Howell system utilizes a custom wiring harness to link the original factory computer and emissions equipment together with the replacement TPI system.
