481X-(Solid no water)Based Engine Packages

Once you start to bump into the 2,500+hp range, the traditional BBC engine platform is living on borrowed time.  When you are ready for the next level of engine platform, the experts at Steve Morris Engines have you covered!  The 481X engine platform was the brainchild of Alan Johnson some years ago.  It brings a tremendous foundation in strength and racer-friendly features.  Steve Morris Engines has continued with the development of this platform, and can provide your race program with a turbocharged or supercharged option.

Engine combinations feature an all-billet AJPE block and the latest-generation billet STAGE-IV cylinder heads (with either a custom turbo or supercharged port design), and we design the remainder of the engine to compliment your racing goals.  We top it off with one of our ever-popular SME billet intake manifolds.   All this from $64,995

If you are ready to have us complete your engine combination, we have options!  Our 3,200+ centrifugal supercharger completion kits start from $34,750 and include your choice of a custom spline-driven setup for a ProCharger F3R-136 or VORTECH 130R, appropriate blow-off valves, methanol-based fuel system including BILLET ATOMIZER injectors, Waterman Racing mechanical fuel pump, an EFI system from HOLLEY EFI or FuelTech, Wilson Manifolds billet 5" throttle body, and custom MSD plug wires.

Our twin-turbo kits start from $38,995 feature a pair of Precision ProMod or Garrett GTX-series turbochargers, TurboSmart wastegates and blow-off valves, clamps and flanges, methanol-based fuel system including BILLET ATOMIZER injectors, Waterman Racing mechanical fuel pump, an EFI system from HOLLEY EFI or FuelTech, Wilson Manifolds billet 5" throttle body, and custom MSD plug wires. 

Once your engine is complete, you have the option to have us dyno-calibrate your engine in one of our two high-horsepower engine dyno cells.  Call to discuss your needs, and how Steve Morris Engines can help get you there!
