Small Block Crate Engines

With the Small-Block as popular as ever, Chevrolet Performance engineers have continued to refine and enhance its performance capability, including adapting contemporary features such as LS-style valvetrain systems on some engines, giving them a broader power range.

ZZ383 Deluxe


Chevrolet Performance engineers continue to refine the classic Small-Block for even greater performance and this power-enhanced ZZ383 crate engine is their latest triumph. Improved Fast Burn cylinder heads and a specific high-flow aluminum intake manifold push horsepower to 450 – a 25-hp jump! Torque increases to 450 lb.-ft.

Ram Jet 350


Chevrolet Performance’s unique Ram Jet 350 combines the classic look of the original Rochester mechanical injection system with the dependability and optimized performance of contemporary port fuel injection. It’s the perfect combination for a resto-mod hot rod.



Chevrolet Performance’s HT383E crate engine is an affordable and more powerful emissions-legal direct replacement for the tired 350 engine in your 1996-99 full-size GM truck or SUV. The larger displacement delivers up to 10 percent more horsepower and more usable torque for effortless towing.



Got a pre-1980 GM truck with a tired Small-Block? Forget the rebuild and take your trusty truck’s capability to the next level with our big-torque HT383 crate engine. Its extra displacement and unique parts are designed to build a wide, flat torque curve that maintains at least 400 lb.-ft. between 2,500 and 4,000 rpm.

350/290 HP Deluxe


The 350 Small-Block is the cornerstone of the performance world and the 350/290 HP is our most affordable – and most popular – high-performance Small-Block crate engine. The 350/290 HP Deluxe adds an aluminum intake manifold* and chrome dress-up kit to create one of the most stylish and value-driven engines on the market.

350 H0 Turn-Key


Forget rebuilding! Our 350 HO is assembled with all-new parts and high-flow heads, giving you more power than just about any production-spec Small-Block ever installed at the factory: 330 hp and 380 satisfying lb.-ft. of torque. It’s affordable power with dependability you can count on.
