    • Inward opening throttle blades improve performance by eliminating part throttle directional influence that causes poor air distribution
    • Shorter height for better airflow, easier packaging for tight hood clearance and reduced weight
    • Brass throttle blades control vibration and reduce thermal expansion
    • Throttle blades attached to stainless steel shafts with aircraft-quality hardware and peened to ensure positive retention
    • Bodies are machined from 6061-T6 billet aluminum for consistent quality, excellent appearance, and light weight

    Can I use this on a chevy 350 engine if I change the intake manifold?

    Asked by: Areapolice
    This could be something you use. There's much more than just this needed.

    Can this be installed on a 1987 V10 with a stock 350 in it? What will I need to make a simple installation?

    Asked by: areapolice
    No that throttle body will not fit that engine.

    Can this item be used with any other manifolds?

    Asked by: Getdown
    This can be used on any manifold that will accept a 4150 style carb flange.
