22. So, we know the Edelbrock E-Street EFI is vastly more high tech than a carburetor, but what about the all-important power gains? After a few quick runs to let the self-learning system tune itself, our 383 stroker made 470 hp at 5,800 rpm and 477 lb-ft of torque at 4,400 rpm. That’s a total gain of 22 hp and 20 lb-ft of torque, as well as a huge amount more area under the curve (meaning more usable power from low RPM to high RPM). On top of that, we’ll be able to get better fuel economy and reliability than a carbureted setup, which is ideal for a daily driven performance truck.
