If I was keeping the motor EFI and using a factory LS PCM then I would probably keep the LS1 alt.
If it were carb and I had the LS1 alt and the brackets fit I would use it. If you have the ford alt you could run it.
In reality there is no right answer. The LS1 doesn`t care if it spins a GM or ford alt, and the battery doesn`t care whose alt charges it. Both the GM LS1 alt and the ford 3G are good designs, the 3G does have more aftermarket support though.
