LS Classic Series Tri-Power crate engines come with the complete line of LS Classic Series components pre-installed and ready to drop-in your classic ride. These crate engines start with a brand new, GM 495 horsepower "Hot Cam" LS3 right out of the box. They are then painted orange or left natural, and are assembled with an LS Classic Series vintage inspired Tri-Power intake kit with dual throttle bodies, chrome air cleaner, billet aluminum valley pan, and big block Chevy style valve covers of your choice. These packages include a Holley Dominator engine management system and wiring harness with a GM electronic transmission controller. Once completely assembled, the Holley ECU is loaded with a start-up tune and the engines are run to check for leaks and oil pressure. Pricing varies depending on the engine's options.
