1989 Chevrolet C1500 Project Rehab: Serious Small-Block Part 2
Topping Off Our 383 Stroker Build With Edelbrock E-Street Self-Learning EFI
Last month, we featured the ground-up rebuild of this tired small-block Chevy engine, which will soon reside under the hood of Project Rehab, our ’89 Chevy C1500 performance truck. With a SCAT Crankshafts complete 383ci stroker rotating assembly, an Edelbrock Power Package Top End Kit, and a Summit Racing Pro Pack oil pan kit, we transformed the ordinary 350 motor into something special. Now, with machining and assembly out of the way, it was time to tie up a few loose ends and add a fuel system before firing it up for the first time.
Choosing a fuel system is no easy task, since there are seemingly countless options available. We wanted a modern small-block that could take on LS-swapped trucks, so picking EFI over carburetion was an obvious first step. Keeping with this modern theme, we also wanted something simple to set up and operate, with a display that allowed us to monitor the engine’s vitals while driving. Edelbrock’s E-Street EFI system ticked all these boxes and more, with control software on a 7-inch touchscreen Android tablet, intelligent self-mapping fuel curves, and a fully assembled, pressure-tested throttle body. It even comes with a pre-terminated OEM-quality wiring harness, so installation would be a snap.

After calling up Edelbrock and ordering a base E-Street EFI system (PN: 3600), we needed to find a shop that could install the system and run our build on an engine dyno for the first time. Superior Automotive Engineering, in Placentia, California, offered to help and even said they would run the engine first with a carburetor for comparative purposes. The guys at Superior are extremely knowledgeable about all kinds of engine work, from thousand-horsepower race motors to simple street builds, so we knew they could get us all dialed in. Follow along to see how our 383 fared on the engine dyno, both with a carburetor and with the new Edelbrock EFI.
