Designed for Gen IV LS heads (L76/L92/LS3 or similar GM Gen IV rectangle port 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. 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. 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 L76, L92 and the LS3 all use the same cylinder head.
