Chevy 383 stroker with 500 HP Hydraulic roller fully forged  bottom end engine combination. This engine can be custom designed to tailor to your specific needs. When we designed this engine combination we had the weekend racer in mind who can drive to the strip and back home. We can also custom paint your engine to match your vehicle at your request. We are a dealer for March Performance serpentine belt systems if you choose them as your pulley manufacture.  We can also assist you in choosing the proper performance street/strip transmission and stall speed converter combination for your vehicle and have it shipped directly to you as your engine is being built.
