Chevrolet Performance 5.3L LS327/327 Deluxe Crate Engine
Vintage displacement and modern technology combine for great performance!
Our affordable LS327/327 Deluxe crate engine has the same 327-cubicinch displacement of the high-revving small-blocks from the 1960s, offering you a great, value-minded retro-fit crate engine for a vintage Chevy or street rod – with 327 horsepower.
It’s based on production 5.3L engines found in GM trucks and SUVs, but Chevrolet Performance engineers gave it a hotter cam, Grafel-coated high-silicon pistons and more. An iron engine block reinforces the engine’s strength and keeps down the cost.
And as one of our Deluxe crate engines, it comes with almost everything you need to get it running, including a high-flow, spider-type intake manifold, ignition coils, coil brackets and more. Add our Holley carburetor P/N 19170093 to finish it off!
