The horsepower you'll gain from efi is negligable. The biggest benefit is being able to run it at greater angles.
And not dealing with carb problems. Thats why im doing mine.
Shoot me a PM if you are interested. I have an EFI kit from an 89. Harness, ECU, the whole think minus the fuel tank. It even comes with everything in the cab and the steering column. Let me know.
