GM Small Block Engines - 2007 Crate Motor Buyers Guide
| LSX 454 CRATE ENGINE | | COMPANY: | GM Performance Parts | | BLOCK: | LSX, iron, new | | DISPLACEMENT: | 454ci (7.4L) | | COMPRESSION RATIO: | 11.0:1 | | CRANKSHAFT: | 4.125-inch, GM, forged | | RODS: | 6.000-inch, GM, forged | | PISTONS: | 4.185-inch, GM, forged | | RINGS: | GM | | ROD BEARINGS: | GM | | MAIN BEARINGS: | GM | | CAM BEARINGS: | GM | | BOLTS: | GM | | HEADS: | GM LSX, aluminum, six head bolts per cylinder | | HEAD GASKETS: | GM | | CAM: | GM hydraulic roller, specs TBA | | LIFTERS: | GM | | PUSHRODS: | GM | | ROCKER ARMS: | GM | | VALVESPRINGS: | GM | | INTAKE MANIFOLD: | no | | THROTTLE BODY: | no | | FUEL INJECTORS: | no | | MAF: | no | | WIRING HARNESS: | no | | PCM: | no | | CORE CHARGES: | no | | WARRANTY: | 12 months, 12,000 miles | | PRICE: | TBA | | COMMENTS: | We’re excited to announce that the same engine that (in prototype form) made 641 hp in the GMPP/Reggie Jackson ’69 Camaro will be available later this year, around the SEMA time frame! By virtue of its incorporation of the new bulletproof GMPP LSX engine block (see a full technical review of this block in our February 2007 issue), features like a six-bolt head pattern, priority main oiling system, and high-tensile-strength cast iron are inherent in the block. Details are still being finalized on this engine, but look for the possibility of a stand-alone EFI system as well. Count on GMHTP to keep you in the loop, as more information becomes available on the LSX 454. |
