In a world where 1,000 horsepower vehicles are common enough that they don’t get nearly as much attention as they did just five years ago, what does it take to get people’s attention? How about double that and throw in a rowdy-sounding ProCharger supercharger? This Procharged LS from Steve Morris Engines does precisely that.
There’s no shortage of high-end big horsepower engine builds at SME. Their LS engines commonly make well above 1,000HP.
Steve Morris Makes The Uncommon Common
Known for building some of the most powerful engines in the world, SME builds can be found in everything from burnout contest cars to some of the fastest street cars in the country competing in drag-and-drive events. Morris prides himself on building durable engines that will live happily at four-digit horsepower levels.
For this particular build, Morris started with a 427 cubic inch block. He filled the block with SME’s hard anodized pistons, steel ring package, and aluminum rods. The 305 cc cylinder heads are from MAST Motorsports and have received the complete SME treatment. This ensures the valvetrain runs happily at 8,000 rpm with the solid roller camshaft. Speaking of camshafts, Morris keeps the details to himself for the most part. The only fact he gives up regarding the bump stick in this engine is that it’s big. “It’s in the 270s and 290s at .050,” according to Morris. This LS is topped with an SME low-profile billet intake that runs dual injectors.
Spinning to 8,000 rpm, this powerhouse easily makes over 2,000HP.
Morris has the engine running on methanol for this dyno session but states that it could be swapped over to run on pump gas. He builds his motors with durability and longevity in mind. So there’s a 21-gallon-per-minute fuel pump feeding the 16 injectors and an SME billet oil pump keeping things lubricated.

A Supercharger Makes Everything Better
The big attention-getter on this 427 LS is the gear-driven F3-121 ProCharger. Although Morris says this engine could be a driver on the street, all of the noise from the supercharger and its gear drive could make in-car conversation difficult. Regardless, it makes the boost necessary to hit the 2,000 horsepower mark relatively easily. With as many high horsepower LS engines as SME is turning out, it probably won’t be long before 3,000 horsepower is somewhat commonplace.
