Here, you can see one of our better EFI pulls compared to the earlier carb numbers. The FAST system made 532 lb-ft at 3,800 rpm and 496 hp at 5,600 rpm. In essence, it lost eight peak horsepower to the carb, but made an additional 6 pounds of twist. I guess we would call that a draw between the two. Where the EFI system excels is in terms of drivability. Where we had to crank to start the engine with the carb the same engine with the EFI system started with a push of a button.
