The Performance Parts division burned a lot of midnight oil to bring this stuff to market. Most of the horn-tooting concerns advancements in the LS and LSX line-up, but there’s a squib or two concerning an honest-to-God body in white, bump-up kits for the 2.0L Ecotec Turbo, and even a big beef transfusion for the 4L65E automatic. NOTE: Some of these parts are so new that there was no time to include them in the ’09 GMPP catalog.

Beginning in the first quarter of ’09, the 2010 Camaro will be offered in “white” packages. The basic unit lists for $7,000 and includes an assembled body structure, including the front fenders, hood, roof, doors, rear quarters and trunk lid. The structure also includes complete floorpans and chassis rails.

Racers must fill out an online application to be eligible to purchase one. The form is available at www.gmperformanceparts.com. Bodies will be sold on a first-come, first-serve basis and there is no limit to the number an approved racing team can purchase.

The body in white includes only an un-painted body shell and no additional components or materials. The bodies do not have vehicle identification numbers, so they may be used only as racing vehicles that will never be licensed for street driving.

“For the racers who would strip down the entire car and replace most of the components with racing-spec parts, the body in white saves time and money,” said Dr. Jamie Meyer. “Drag racers, for example, won’t have to worry about swapping out for a solid axle – they can just bolt one up and go.” The body in white’s unadorned interior also saves time and money by allowing racing teams to eliminate the process of stripping a fully equipped production car in order to reduce weight and prep the chassis for a roll cage.

LSX376 (PN 19171049) The LSX376 combines the LSX Bowtie block with the production LS3 engine’s high-flow, L92-style cylinder heads and camshaft. Unique, forged-aluminum LSX pistons also are part of the assembly and special LSX376-logo valve covers distinguish the new crate.

When fitted with a production LS3 intake manifold and injection system, the LSX376 is capable of producing approximately 450hp and 430lb-ft of torque. It can also be fitted with a carbureted induction system that can be tuned for greater power. The manifold and carburetor are available from GMPP.

LSX454 (PN 19166972) – The LSX454 crate engine uses the LSX Bowtie block, an all-forged, super-tough rotating assembly and new, deep-breathing LSX six-bolt cylinder heads. It is topped with a high-rise intake manifold and four-barrel carburetor and is rated at 620hp and 600lb-ft of torque. It comes in Deluxe form, so it includes everything from the carburetor to the water pump as well as all-new orange powder-coated valve covers with “LSX454” logos.

When GMPP introduced the LSX Bowtie block two years ago, it was the first stage in the rollout of a family of ultimate-performance engines and components. The components are used in GMPP’s new LSX crate engines and are available individually. The components include forged crankshafts, forged connecting rods, forged pistons, six-bolt cylinder heads, intake manifolds, and a camshaft.

The crankshafts, connecting rods and pistons are forged, while the high-flow LSX cylinder heads are based on the LS7 design, but incorporate six-bolts-per-cylinder for unmatched clamping power. All of the new LSX parts were approved for release only after they completed a rigorous development and validation program. That includes 50 hours of continuous, full-load operation on a dyno before any part is approved for sale.
