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 No.4150 throttle bodies.

The LS3, L92 and L76 all use the same cylinder head. L92 heads are only compatible with a 4.00in and larger bore diameters, smaller bores (including most 5.7L blocks) will require valve reliefs cut into the block. Throttle Body Recommendations: Edelbrock No.38783. Installation Notes: Uses LS3/L76/L92 style individual port O-ring seals GM PN19256623, L92 heads are intended for 4.00in bores and will not work with 5.7L blocks without valve reliefs. Manifold Dimensions: R-1.85in, F-0.57in, H-2.42in, CH-7.40in, CA-0. Carb height (CH) for this manifold is measured from the valley cover flange to the carb pad.
