350 HO Deluxe (#19433038)

A 350 that's been stepped up in power!

You won't go broke finishing off your project car with our 350 HO Deluxe crate engine! It's packed with all the features you need to get a reliable 330 horsepower and 380 lb.-ft. of torque from a dependable, time-tested combination of GM Performance Parts. Of course, all of the components used in this engine are brand new – not re-manufactured parts like the competition is trying to sell you. Designed by our in-house engineers to give you maximum return for your hot rod dollar, the 350 HO Deluxe is a great choice for your small-block crate engine needs.

The 350 HO is based on a tough, Chevy four-bolt block that holds a strong nodular iron crankshaft, good rods, and aluminum pistons. The high-lift camshaft gives the engine its own unique, aggressive idle. The cam is based on the same one found in 1965-67 Corvette 327 engines, but it has even more lift and duration.

Complete from top to bottom, the 350 HO comes pre-assembled with the intake manifold, carburetor, and distributor.

The next chapter of Small-Block performance

SP383 Deluxe (#19432114)

More power from our classic Small-Block stroker

Chevrolet Performance’s big-torque SP383 Deluxe is more powerful than ever. We’ve added revised cylinder heads that incorporate a new, high-rpm valvetrain to help the SP383 Deluxe produce 435 horsepower and 445 lb-ft of torque. The new, lightweight aluminum cylinder head casting is based on the proven Fast Burn design, with large intake runners and 2.00-/1.55-inch valves. New beehive-style valve springs enable greater high-rpm performance and durability. They allow the SP383 Deluxe to rev higher, building more power to complement its low-rpm torque. The SP383 Deluxe is built with a brand-new block with four-bolt mains. It also features a forged-steel crankshaft, an aggressive hydraulic roller, camshaft, and durable, high-silicon pistons.

Unique valve covers distinguish the engine from previous versions and it now includes a high-flow, aluminum intake manifold. Use the Holley 770-cfm four-barrel carburetor (P/N 19170093) to make the most of the engine’s capability and achieve the listed horsepower and torque ratings. Your Chevrolet Performance dealer has everything you need to finish off the engine and get this small-block stroker running in your vehicle faster.
