Edelbrock Victor Jr LS3/L76/L92 GM EFI Intake Manifold GM LS Engines
Designed for Gen IV LS engines equipped with LS3, L92 and L76 cylinder heads, this manifold is for EFI or carbureted racing applications operating between 3500-7500 rpm. This manifold uses a standard square-bore carb flange that is compatible with both Edelbrock EFI intake elbows and single bore 90mm throttle body or four-barrel #4150 throttle bodies. EFI manifold #28455 has additional bosses and machining that allow for the use of fuel injectors when combined with the #3638 fuel rail kit (sold separately. The LS3, L92 and L76 all use the same cylinder head. L92 heads are only compatible with a 4.00" and larger bore diameters; smaller bores (including most 5.7L blocks) will require valve reliefs cut into the block. Throttle Body Recommendations: Edelbrock #38783. Installation Notes: Uses LS3/L76/L92 style individual port O-ring seals GM PN19256623, L92 heads are intended for 4.00" bores and will not work with 5.7L blocks without valve reliefs. Manifold Dimensions: R-1.85", F-0.57", H-2.42", CH-7.40", CA-0°. Carb height (CH) for this manifold is measured from the valley cover flange to the carb pad.
