Chevy 427 small block stroker with 550HP 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 CVF Racing 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.

MSD Street Fire CD Ignition
MSD Street Fire CD ignitions are perfect for budget-minded enthusiasts. Street Fire CD ignitions offer capacitive discharge technology that fires a series of multiple sparks for 20 degrees of crankshaft rotation when the engine is running under 3,000 rpm. This ensures complete combustion and produces great throttle response with a smooth idle. MSD’s Street Fire CD ignitions are built within a durable cast aluminum housing and easily connects to points, amplifiers, and magnetic pickup distributors. There’s even an adjustable rev limiter (100 rpm increments) for overrev protection!
This system includes the following items:
- Ignition Control Module; Street Fire CDI
