Bottom end is pure Manley muscle:
• Manley crank
• Manley rods
• Manley pistons
• Manley camshaft

All of it locked down with ARP bolts while a Melling oil pump keeps everything happy with a rock-solid 66 lbs of oil pressure.

The valvetrain is equally serious — Trend pushrods, Johnson lifters, and T&D shaft rockers with roller tips keep everything stable and precise under extreme load.

Up top you’ve got MAST Performance heads flowing serious air, and the real chaos maker: a Whipple 4.5L supercharger force-feeding the motor with 11 lbs of boost.

The results?
1,200 horsepower at 6,000 RPM
1,081 lb-ft of torque at 5,000 RPM

That means brutal mid-range pull and a top-end that will pin you to the seat. This thing doesn’t just make power — it makes power the hard way, under boost, with strength built into every rotating assembly part.

It’s loud. It’s mean. It’s ready to punish tires and egos.

LS3 with Whipple Superchargers GEN 6 3.0L Inverted Hot Rod Supercharger

We’ve topped a rock-solid GM LS3 6.2L with a low-profile Whipple inverted supercharger and dressed it out with a razor-sharp Concept One Pulley Systems 10R 10-rib pulley system. Perfect hood clearance, serious boost, and that signature twin-screw howl.

To handle the boost we lowered the stock compression with Cometic Gasket, Inc. head gaskets and fully reinforced the bottom end and top end with ARP head, main, and rod bolts. The result? Instant tire-shredding torque the second you plant your foot… clean billet looks… street manners by day, absolute animal by night. Tuned and ready for reliable 750 hp performance.

Turnkey Engine Package Price: $24,900
Includes the complete assembled supercharged engine, Concept One billet serpentine system, custom wiring harness, programmed ECM, application-specific oil pan, valve covers, and all the supporting components needed for a drop-in ready install.
