General Motors LS and LT line of V8 engines are perfect for engine swaps. With a compact design, good reliability, low cost and great power and torque, the GM LS V8 and LT V8 are used in all sorts of custom builds – from Pro Touring-style muscle cars, to drift cars, drag cars and just about any other type of performance vehicle you can think of.
The engine retrofit specialists over at Speartech are now offering a way to make the GM LS V8 or LT V8 swap even easier. The company’s new turn-key crate engine and transmission packages come pre-assembly and ready to drop into the appropriate car, truck or SUV.
Speartech offers crate engine packages for the supercharged 6.2L LT4 V8, the more powerful supercharged 6.2L LT5 V8 as well as the naturally aspirated 6.2L LS3 V8 and 6.2L LT1 V8. The LS3 crate engine will come with a six-speed 6L80 automatic, while the LT1 can be ordered with a 6L80, eight-speed 8L90 or 10-speed 10L80. The supercharged LT4 will come with an 8L90 or 10L80, while the LT5 will come with a 10L80.
As a reminder, the LS3 V8 is good for 430 horsepower, while the LT1 produces 455 horsepower. The LT4’s output differs depending on the application but makes 650 horsepower in the Camaro ZL1, while the LT5 is good for 755 horsepower.
“All packages are brand new and include all sensors, programmed computer modules, throttle pedal, and front O2 sensors,” Speartech says of its turn-key kits. “Our engine packages include Speartech engine/transmission control system, built entirely on your engine for a precise fit, and we test run each one upon completion to ensure everything works perfectly.”
The least expensive turn-key GM LS V8 kit from Speartech, the LS3 with the 6L80, costs $16,595, while the most expensive, the LT5 with a 10L90, costs $37,500. Head on over to the company’s website for more information on these create engine kits or to place an order.
