LS1 water pump on 5.3 Vortec
Hi guys, I am swapping a 5.3 Vortec into my 1985 S10 pickup. The motor is in but I had to notch the frame to lower the engine so the hood closes without hitting the throttle body and intake and relocate the alternator also. The problem I have now is the water pump outlet on the Vortec water pump discharges on top of the water pump and is higher than the radiator fill cap and this will only trap air and the system will may never bleed the air out. I have seen pictures of LS1 water pumps and their outlet is straight out the front rather than on top and it is below the filler. Will this water pump work and can I drill and tap a hole directly over the outlet for a coolant fan switch to operate the cooling fans. Any opinions or help would be appreciated. Thank You.

Lots of people use the LS3 camaro water pump because it uses truck spacing.
