General Motors has discontinued the supercharged 6.2L LT5 V8 crate engine, which was first introduced by Chevrolet Performance at the 2018 SEMA Show in Las Vegas.
The 6.2L LT5 V8 was only ever offered in the 2019 Corvette ZR1 before Chevrolet Performance began offering it as a crate engine in late 2018. The most powerful engine offered in a Chevy production vehicle, the LT5 produces 755 horsepower at 6,400 rpm and 715 pound-feet of torque at 3,600 rpm. The heart of the LT5 is the larger Roots-type supercharger, which is based on the same effective design as the LS9 and LT4 engines, but with a larger displacement of 2.65 liters and a higher boost pressure of 14 psi. GM suggested the crate engine be used in pre-1973 vintage car builds, or off-road vehicle applications.
Chevy debuted the 6.2L LT5 V8 crate engine by dropping it in a 1973 Chevelle Laguna show car for the 2018 SEMA Show in Las Vegas. Inspired by NASCAR stock cars, the build also featured a racing-inspired front splitter and rear spoiler, 18-inch wheels with red sidewall Goodyear tires and a carbon fiber hood inspired by the 2019 Corvette ZR1’s.
It’s not clear why General Motors has decided to pull the plug on the LT5 after only a couple of years of sales. Sales of the crate engine were likely minimal, though, as it retailed for a steep $19,995. The automaker also sold less than 3,000 examples of the 2019 Corvette ZR1, so with its demise, it seems as though the LT5 V8 crate engine is set to become one of the rarest modern-day GM production engines.
With the 6.2L LT5 V8 engine’s demise, the most powerful Chevrolet Performance crate engine now is the 6.2.L LT4 V8, which produces 650 horsepower and 650 pound-feet of torque. Customers can purchase the LT4 V8 through a certified Chevrolet Performance dealer, which they can find via the automaker’s website.
