1973 Chevrolet Chevelle LT5-Powered Laguna Showcases Chevy’s New Crate Engine

At this year’s SEMA Show, Chevrolet Performance is going to unveil their newest crate engines, and what better way to do that than to put them into vintage vehicles? One such vehicle will be a 1973 Chevrolet Chevelle, which will feature the LT5 6.2L supercharged crate engine.

The ’73 Chevelle Laguna made its mark in NASCAR and in the world of muscle cars. While Cale Yarborough was driving into the winners’ circle, Chevy fans were loving the more contemporary lines of the Laguna. That performance and style are continued in the refitted Laguna, but there’s a flair of the new as well. The LT5 is the same engine that you’ll find in the Corvette ZR1, and it’s been described as the most powerful production engine ever from Chevrolet. The LT5 is rated at 755 horsepower with a torque rating of 715 lb-ft. The engine is a first with Chevy, being the first to have a dual-fuel system. Direct injection and supplementary port injection, as well as a new larger displacement supercharger, amp up the power on this engine.

Chevy’s new engines, which also include a ZZ6 EFI 5.7L V8 and an L96 6.0L V8, bring the auto manufacturer’s engine portfolio up to nearly 50 small block, big block, LS, LSX, LT, Circle Track, and COPO engine crates. You can see these engines for yourself at SEMA on October 30 through November 2.
