VORTEC 8100 / 8.1L / 496CID GEN7R INTAKE MANIFOLD

NOTE: Average ship within 6-8 weeks from order date.

The stock 8.1 liter intake manifold was designed for low RPM use and cannot meet the high-RPM air flow demands of the 496 / 8.1 liter engine in performance applications. 

The Raylar GEN7R intake manifold has been engineered for one purpose, maximum airflow and power output. We designed the GEN7R intake manifold to provide better airflow and optimized performance while still functioning as a drop in replacement or the restrictive stock intake manifold. It's design that allows it to bolt on in the same space as the stock manifolds, and accepts all standard fittings, sensors, brackets, injectors, fuel rails, and accessories without additional modifications to the engine or its wiring. Raylar's GEN7R intake manifold incorporates shorter length, high velocity, tuned runners to produce stronger mid-range torque and higher RPM horse power with a large, unrestricted plenum to satisfy this engine’s demand for more air at higher RPM’s. The Raylar GEN7R intake manifold adds an additional 30% in air volume over the stock manifold, which means proper breathing at high RPM and big power gains across the entire power band - especially in modified applications.

The aluminum intake manifold for the 7th generation big block Chevy is engineered to maximize the horsepower and torque levels of the 496 / 8.1 liter Vortec engine when used with performance cylinder heads and camshafts.

(4 bolt / LS2) accepts both 90MM & 102MM throttle bodies.
