Back in 1957, Chevrolet’s 283/283 V8 engine with its new fuel injection system was capable of providing 1 horsepower per cubic inch. Fifty years later, Chevrolet’s top engine is the LT5 single-cam pushrod V8 that has an output of 2 horsepower per cubic inch!
For the tidy sum of $17,915.00 your next project car can have the same 755-horsepower and 715 lb-ft of torque that is found in the 212+ mph Corvette ZR1!
And don’t forget the GM Performance Cold Air Intake which can add an additional 17 horsepower if the 755-hp isn’t quite enough.
Codenamed BAS (Big Ass Supercharger) by Chevy’s engine builders, the LT5’s supercharger is 52% larger than the LT4 found on the Z06. The new supercharger design with its twin intercoolers raised the height of the intake plenum by nearly 3 inches, which necessitated the ZR1’s halo-hood design to allow for more visibility.
Although the LT5 crate engines are the same as those found in Chevy’s supercar, don’t expect to see the beautiful carbon fiber engine covers as seen on the ZR1!
You can order your own LT5 from the parts counter at any authorized GM Performance Dealer. The engine comes with a two-year, 50,000-mile factory warranty.
