HEAVY-DUTY LS POWER FOR YOUR TRUCK!
Chevrolet Performance’s L96 6.0L crate engine is based on the same work-ready powerhouse offered in Silverado HD trucks – and it’s ready to go to work for you in a late-model truck or project vehicle that needs a fresh engine or a dual-purpose vintage truck built for work and fun.
Thanks to the advantage of its high-flow cylinder heads and other technologies, the L96 offers more than 50-percent more horsepower than the 454 Big-Block offered in Chevy trucks from the 1970s through the early 1990s. It delivers more torque, too, than most production 454 engines, while cranking it out it in a lighter, more compact package.
Chevrolet Performance’s inclusive crate engine kit includes the engine assembly with a production high torque intake manifold, throttle body assembly, ignition coils, water pump, balancer and more. You’ll need to add a frontend accessory drive system and an engine controller, but we’ve got that covered, too.
For all L96 crate engines (12677741), use Front End
Accessory Drive (FEAD) kit 19369108, as noted in 2018 Chevrolet Performance
