The original fuse block is the 86 fuse block.

I thought this was a neat idea.

Do you notice the outlet on the waterpump is on top for the truck and going out the front on the camaros. Well I saw a swap that used the LS1 engine and the LS1 waterpump. So, the outlet was coming out the front. Now you see that air bleed outlet on the top corner front of the head that usually goes through the throttle body, then to the top of the radiator. That line was ran differently. The top of the waterpump, where the truck outlet usually goes, was tapped with a 1/8" fitting and the air bleed tube on the head went to the top of the waterpump, which is a lot easier than trying to run it to the radiator if you're doing an obs swap and don't have the nipple on the radiator for the hose.
I have the truck waterpump and I'm going to tap the front of the water pump, where the camaro waterpump outlet is, then run my airbleed to this fitting. I'll just need a small 1/8 90deg brass fitting to make sure it points up to the air bleed.

The swap looks great!! Get ready to haul ass!!
