Inside the LSX454
The LSX454 crate engine has the displacement of Chevrolet’s legendary 454 big-block packaged within the small-block dimensions of GM’s LS engine family. It uses GMPP’s standard-deck LSX Bow Tie block for strength and is filled with an all-forged, rotating assembly—and bore and stroke dimensions of 4.185x4.125 inches. Breathing is handled by GMPP’s exclusive LSX six-bolt cylinder heads, which provide greater clamping strength over production-style four-bolt heads.
On the outside, the engine is dressed with distinctive orange powdercoated valve covers with engraved “LSX454” logos. (The valve covers do not include mounting provisions for ignition coil brackets. Aftermarket or custom relocation brackets must be obtained.)
The LSX454 is manufactured with the same, heavy-duty eight-bolt crankshaft flange used on the supercharged 6.2L LSA engine that’s found in the Cadillac CTS-V series. Like the six-bolt heads, the eight-bolt pattern of the crankshaft flange offers greater clamping power, but requires a flexplate adapter for use with popular automatic transmissions, such as the Hydra-Matic 4L80-E.
Additional installation notes for the LSX454 include:
• The LSX454 is delivered without an oil pan (a temporary dust shield is installed at the factory). GMPP’s Muscle Car Oil Pan Kit (PN 19212593) fits most ’55-95 GM front-engine/rear-drive vehicles.
• One of GMPP’s frontend accessory drive (FEAD) kits is required. They include the alternator, power steering pump, their mounting brackets and pulleys, hardware, and, on some kits, an air-conditioning compressor.
• Aftermarket engine mount brackets must be used to install an LS engine in a vehicle that wasn’t originally equipped with one.
• GMPP recommends the LS1 Engine Installation Guide (PN 88959384), which illustrates basic procedures and offers helpful tips on installing an LS engine in older vehicles.
Both the new LSX454 completion kit and the LSX454 crate engine have warranties. The completion kit is backed by a 12-month/12,000-mile limited warranty and the LSX454 crate engine carries a 24-month/50,000-mile limited warranty. See complete details at gmperformanceparts.com.
Todd Gartshore’s Life Honored at NMRA/NMCA West Coast Shootout
A moment of silence for Todd Gartshore was held at the NMRA/NMCA West Coast Shootout event on July 9 at Auto Club Dragway in Fontana, California, while the Centerforce Camaro made a lap around the autocross displaying a checkered flag. Gartshore, co-owner of Baer Brake Systems and a major supporter of SEMA and the performance aftermarket for decades, died just prior to this event where he planned to participate in Baer’s Speed-Stop Challenge. Many of Gartshore’s best industry friends were on hand at this event as part of a special Racers Against Street Racing promotion where media and manufacturers raced with street-type racers to promote taking racing off the streets and putting it on the track where it belongs. A special picture of Gartshore was displayed all weekend where friends could write a special message in his memory. The picture was presented to the Baer Brake Systems team at the event and will be on display at their headquarters in Arizona. Present in this photograph are the Baer Brake Systems’ team, the Centerforce team, Doug Dwyer of Power TV Media, Mike Santa Cruz of NMRA/NMCA, and SEMA board members, John Hotchkis and Steve Wolcott.
