Engine - Intake Manifolds - Aluminum Intake Manifold

From GM Performance - This Gen II design small-block (RPO LT1 type) will fit late model Corvette, Camaro/Firebird, and Caprice engines. With the longer runners, it can increase engine torque by 30 lb/ft. without sacrificing top end horsepower. This will allow enthusiasts to take off the advancements of the Gen II engine's design without installing a computer pre-emission controlled vehicles. Technical Notes: The bolt pattern on this manifold flange was revised and the holes rotate 27 degrees to match the GEN II cylinder heads. There are no water coolant holes on this manifold, and it will only fit 1991 or later Gen II engines. Casting P/N 24502574.

From GM Performance - The LT4 aluminum manifold is the same as the LT1 (P/N 24502592) except this manifold is used on 1996 LT4 design engines or cylinder heads. The intake ports are .0100 inch higher than the LT1 design engine. Use intake manifold gasket P/N 12367777. Casting P/N 24502574.

From GM Performance - Fits 18 degree head PN's 10134363 and 24502482. This aluminum intake manifold was developed for NASCAR's shorter tracks and has smaller runners and less plenum volume than the 10185053 to enhance midrange torque. This manifold has worked well on trans-am engines.

From GM Performance - this light-weight aluminum racing manifold is 10 pounds lighter then the original short track casting P/N 24502481. This new light weight design reduces weight where the impact on handling is greatest, high and forward in the chassis. This manifold's port volumes and runner shapes duplicate a professionally prepared manifold and requires only minimal preparation for top performance. This manifold is recommended for 310ci road racing and 358ci short track engines. Technical Notes: see P/N 24502481 for more details.

From GM Performance - This aluminum manifold is a revised version of the original Bow Tie intake. Material was removed from the outer walls of the four middle runners for an improved line of sight path to the cylinder heads intake port. Aluminum was also added to the walls to provide more raw material for porting. This updated manifold is designed to enhance mid-to-high RPM power.
