Tuned Port Injected engines with Vortec heads is a reality thanks to this Vortec manifold. Engine dynometer tests have shown a 50HP gain with the new SDPC Vortec TPI base plate and stock Vortec heads versus the stock L98 engine. The Vortec TPI base manifold was designed from the original GM TPI intake to be a universal fit for Chevrolet/Pontiac cars (1985-92) that were equipped with factory Tuned Port Fuel-Injection and the cylinder heads have been replaced with the new style raised-port improved flowing Vortec heads from Chevrolet Performance

PERFORMANCE GAINS
In house testing has proved a gain of 50 horsepower over a stock L98 engine. The larger runners of the TPI Vortec Baseplate combined with the excellent flow characteristics of the GM Vortec heads produced 300 hp on an otherwise stock L98 engine. Other modifications such as camshafts, rocker arms and injectors produced as much as 385hp with the stock computer and stock throttle body.
