Designed for Gen IV LS engines equipped with L92 cylinder heads, this manifold is intended for EFI racing applications operating between 3,500 - 7,500 rpm. This manifold uses a standard square-bore carb flange that is compatible with both Edelbrock EFI intake elbows and throttle body or four-barrel throttle bodies. L92 heads are only compatible with a 4.00" and larger bore diameters; smaller bores (including most 5.7L blocks) will require valve relief cut into the block.

• Manifold has additional bosses and machining that allow for the use of fuel injectors when combined with the # ED3638 fuel rail kit.
• Made in USA
