GRAND BLANC, Mich. – GM Performance Parts (GMPP) will auction the first production LSX454R crate engine at the Barrett-Jackson Scottsdale event this month, with the proceeds going to the American Heart Association.

The charity sale is scheduled for the evening of Friday, Jan. 21, and will be carried live on SPEED’s coverage of the Barrett-Jackson auction. The engine carries lot number 1032.1 and bids can be submitted at the auction in person or online.

“GM Performance Parts is thrilled with the opportunity to leverage our high-performance engine, the heart of a vehicle, to help prevent heart disease and stroke,” said Dr. Jamie Meyer, product integration manager for GM Performance Parts. “This sale gives the highest bidder the opportunity to buy the first production version of the most powerful small-block V-8 ever engineered by General Motors.”

“The American Heart Association is honored to work with partners like General Motors, who exemplify corporate citizenship,” said Heather Kinder, executive director for the Southeast Michigan American Heart Association. “This donation further defines GM’s commitment to improving the health of our community.”

Over the years, GM and the GM Foundation have contributed more than $1 million to the American Heart Association.

GMPP’s presence at Barrett-Jackson also will include a display of crate engines, engine parts and project vehicles, including E-ROD emissions-compliant crate engine systems. The Lingenfelter custom ’55 Chevrolet pickup truck featuring the 5.3 E-ROD crate engine (part number 19258004) and the Superformance '63 Grand Sport Vette with the LSA E-ROD crate engine (part number 19257460) will be showcased.

LSX454R details
The all-new LSX454R crate engine (part number 19257880) is officially rated at 750 plus horsepower and 680 lb.-ft. of torque. It was developed for drag racing, bringing together many of the specialized GMPP LSX parts racers are already using, including the robust LSX Bowtie block.
