The first example of GM’s LSX454R crate engine is set to be auctioned on Jan. 21 at Barrett-Jackson for charity, with all its proceeds to be donated to the American Heart Association. The 620hp that’s delivered by the LSX454 is very impressive but the LSX454R offers quite a bit more with an output of 750hp.
Last month, GM Performance Parts rated the engine at 720-plus-horsepower and 720-plus-pound-feet of torque, but with the 7.4-liter about to hit the auction block, the figures have been officially revised to 750hp and 680 pound-feet of torque.
Dr. Jamie Meyer, product integration manager for GM Performance Parts, said that GM Performance Parts is “thrilled” with the chance to leverage its high-performance engine to help prevent heart disease and stroke.
What the winning bidder gets is the first production version of the most powerful small-block V-8 ever engineered by General Motors. For many years, GM has been supporting the AHA, and its charitable arm, the GM Foundation has handed more than $1 million to the AHA.
Heather Kinder, executive director for the Southeast Michigan American Heart Association, remarked that it was an honor for the American Heart Association to cooperate with partners like General Motors, which is known for its corporate citizenship.
Kinder added that the donation represents GM’s commitment to improve the health of the community. For the past years, GM and the GM Foundation have donated over $1 million to the American Heart Association.
With GM Performance Parts’ presence at the Barrett-Jackson confirmed, the auction will feature a display of crate engines and engine parts as well as project vehicles like the E-ROD emissions-compliant crate engine systems.
Also to be showcased are the Lingenfelter custom 1955 Chevrolet pickup truck powered by the 5.3 E-ROD crate engine (part number 19258004) and the Superformance 1963 Grand Sport Vette with the LSA E-ROD crate engine (part number 19257460).
Product experts will be present during the entire event to answer questions on how to build their dream car. Developed for drag racing, the new LSX454R crate engine (part number 19257880) provides more than 750 hp of output and 680 lb.-ft. of torque. It features several specialized GMPP LSX parts that racers have been using like the LSX Bowtie block.
Engineers at GMPP designed the LSX454R to suit the high-rpm demands of drag racing, using new LSX DR cylinder heads (part number 19166979) for a high-compression, solid-roller combination. It comes with 11-degree, six-bolt aluminum heads with raised ports, thereby allowing for superb airflow. These aluminum heads are complemented by a Holley 1,150-cfm Dominator carburetor as well as a new high-rise open-plenum intake manifold.
