LT-4 Crate Engine | 6.2L Supercharged

Description

Originally designed for the C7 Corvette, Chevrolet Performance offered a limited number of LT-4 crate engines.  Generating 650 horsepower and 650 Ft-Lbs of torque, the LT-4 makes exceptional power.  At only 376 cubic inches, the LT-4 puts out more than 1.7HP per cube.  There are many ways to make that much power and more, but the LT-4 has been extensively engineered by Chevrolet to be full streetable. We have driven LT-4 engines and the experience is best described as refined and exciting. This is a brand new, never run, never installed crate engine. It is sold”In The Wrapper” with protective covers and original crate. The build plate is engraved with a serial number “05/2025” build date. FYI: The super-cool build plate is made of metal and is glued to the back of the engine. It can be removed and relocated for display on your firewall, core support, dashboard, etc.

**** NOTE: This engine is DISCONTINUED. Do NOT respond to anyone pretending to sell engines as Kilgore Kustoms on Tik Tok. Kilgore Kustoms is NOT on Tik Tok.****
