Were you happy with the performance and manners of the EFI'd .509 otherwise? A wider LSA cam should make the EFI happy and help with MPG, which I would expect is a factor with an OD trans and a 3.54 gear.
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.
