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.

**Customer Review of our Chevy 383**

  
Steve,

My name is Clint Booth I purchased a 383-500 hp stroker. My 79 z28 had a 383, but the engine that ya'll built for me absolutely blows the old one out of the water. There is no comparison! I am more than pleased. Big thanks to everyone at Proformance Unlimited! You guys do amazing work!! I look forward to doing more business with you in the future!

P. S. I have attached some photos, and I plan to have a burnout clip your collection soon Thanks again!!

Fuel Delivery Systems


The Atomic EFI outshines the competition in ease of installation and performance! The MSD annular ring injection design produces an air/fuel charge with much better mixture as well as an even distribution among the cylinders that our competition cannot match. Better AFRs equal better idle quality, better starting, and better overall drivability throughout the rpm range. You and your engine will be glad when you Go Atomic.


 Kit Includes:

  • Throttle Body Assembly (An exact swap for a 4150 Holley)
  • (4) port style injectors
  • EMS (Engine Management System)
  • Comprehensive Instruction Manual
