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.
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.
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.
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.
