Chevy SBC 350 Shootout +Plus 1957-95 High Rise Intake Manifold Polished

Speedmaster 746-PCE147.1026 Features:

After extensive development we have a manifold that outperforms the standard shootout manifold. Depending on the specific engine combination we have seen as much as 20 extra horsepower over the standard Elite manifold. Note that this extra power is mostly showing up over 7,000 rpm. So if you aren"t turning your engine in the 7,000 to 8,000 rpm range, stick with the standard elite manifold. Below 7,000 this manifold is only 3 or 4 more horsepower better.

• Step up to the high-rpm power of an open plenum
• Design for racing applications or for serious street performance
• Cast from steel molds for a tighter grain and reduction of porosity
• Pressure tested to ensure maximum performance
