Overall, the EFI tuning is not quite where the carb was yet. But with the carb, you could lug the engine down to 45 MPH in 5th gear (.64 OD), and while it was no powerhouse down there, it would pull smoothly. I'd have to think that a camshaft with a wider LSA would, at the very least, have the potential to match or slightly improve upon this characteristic.
So you're saying at lower RPM your carb was performing better than your EFI system is? If that is the case, I think you first need to determine why you are unable to meet or exceed the street manners of the carb. IMO cam selection is not the problem.
