If the extra room becomes critical, look into the early (1998-2003) camaro style water pump and related accessory drive system. It does not have the treads, and it is 3/4 of an inch closer to the block than the "Truck Style" setup you currently have (you will gain approximately 1 1/2 inches going to this style). Eric and I did the reverse on the gto restomod. We used the truck spacing (which is currently on your engine), and then went with the camaro/corvette waterpump to make routing the hoses easier. To do this you have to purchase a 3/4 inch spacer that pushes the camaro/corvette waterpump out so the pulley lines up with the other truck pulleys. If you think you may want to try this, let me know, I can post pictures of the Camaro/Corvette setup and the truck setup with the spaced outward water pump. Good Luck!
