Pace Exclusive ZZ383 430HP Engine with 8-Stack EFI

Pace Exclusive ZZ383 430HP Engine with 8-Stack EFIWe took the new 8-Stack fuel injection system and mounted it on a brand new Chevrolet performance ZZ383 then added a FAST EZ-EFI ECU and harness. The Dyno results where surprising with 430HP @ 5200 RPM & 475 ft. lbs. of torque @ 4300 RPM. More surprising was tight air fuel ratio reading which stayed between 13.3 & 13.6 throughout multiple pulls on the dyno. During pull number 2 the FAST system started learning and making self-adjustments which further enhanced the engine’s performance. This fuel injected ZZ383 is one of the most efficient performance small block Chevy engines in our stable. We plumb the injection system with the new TechAFX premium fuel injection hose and fittings to provide you with long term reliability and each of these ZZ383 engines get dyno tested to insure proper engine break-in and trouble free installation.
