I've already drilled and tapped the block, and have the alternator off of my 5.3L mounted in place. I will only be running that and a F-body water pump and tensioner, and F-body balancer. I already have everything but I haven't mounted the balancer or water pump yet.

My question is ........ With the 5.3 alternator in the F-body bracket will the pulley line up where it needs to be or do I need to buy an F-body alternator?

If its the small truck alterbator it will work. They just don't have the boss on the back for the small reinforcement bracket can't be bolted on.

The rear mount is beneficial when mounting on an iron block though I have never tried it without. Check out a late 90's Savana/Express van alternator. It has the rear mount similiar to the LS1, it might fit and it costs much less.
