Chevy has quietly discontinued the most powerful crate engine in its arsenal, the 6.2-liter supercharged LT5 V-8. If you want big Chevy power for your next build, you'll have to find something that isn't in Chevy's official parts catalog.
The news, first spotted by Motortrend, comes roughly three years after the company introduced plans to offer the motor as a standalone product. It even built a one-off 1973 Chevelle Laguna to SEMA in 2018 to show off the engine's versatility. An evolution of the supercharged LT4 found in the C7 Corvette Z06, it made 755 hp and 715 lb-ft of torque thanks to a bigger supercharger and a host of other upgrades.
In addition to being the flagship of Chevy's crate motor program, the LT5 also had a home in the C7-generation Corvette ZR1. Meant as a sendoff for that generation of Corvette, it was good enough to win our Performance Car of the Year comparison test for 2019. That should give you a good idea of how impressive this engine really was.
Those still in the market for boosted Chevy V-8 power will be pleased to hear the automaker still offers the 650-hp LT4 as a standalone product, which should be plenty for most builds. Nonetheless, it's always a sad day when there's one less new V-8 in the world.
