Holley 300-256 Cathedral Port Race Intake Manifold Carb LS1 LS2 LSX Free T Shirt

Description: SCRAM SPEED is a real perfromance shop in Mahomet Illinois. We install, tune, dyno and race what we sell. FINALLY! A viable alternative to the Edelbrock Victor Jr or Super Victor where you don't have to spend a fortune. We've seen good gains on our in-house chassis dyno versus the Brand E intakes with this new race intake. This is an easy way to add some power to your cathedral port combo, just be aware that the intake is taller than the Edelbrocks... We include a **FREE LSX T-shirt with purchase**. Size defaults to large. If you require a different size please message us with the size you need. We will substitute as stock allows. We carry M-2XL. The new Holley Single-Plane Race intake manifold were designed with performance in mind. They feature a race bred, two piece split feature that was previously only found on the most expensive race intakes. The manifold will fit GM LS Gen III engines with cathedral port heads and are intended for 4150 style square bore flanged carburetors or throttle body EFI. The LS Race single-plane intake manifold was designed for hi-performance/racing engine applications, 5.3 to 6.2+ liter displacement, and maximum engine speeds of 6000-7000 rpm, depending on the engine combination. This single-plane design provides optimal performance across the RPM spectrum while providing maximum performance up to 7000 rpm. The Holley LS Race manifold incorporates a split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, making custom porting and matching a snap. With shoulder bolt locators and O-ring seal, reassembly is simple and precise.
