Default LS1 water pump with truck acc's?

Has anyone used a LS1 water pump with the LM7/LQ4/9 truck acc bracket and acc's?

It will not work. The truck accessories sit too far out.

I know the the offset of the belt is different, but I thought that the large bell on the LS1 water pump would still make it feasable...

Yeah, that's why I am asking if you can change only the pump. Those spacers look nice, where did you get them? Did you just used two sets (4) water pump gaskets and longer bolts? Did you still torque it to 22 ft.lbs?

pm the guy on the link.red. it comes with the longer bolts and the spacers. u will need the 4 gaskets though.i think i paid 85 or 75 shipped dont remember. It was alot cheapier then changing the whole setup to f-body or c5 accessories.
Not the best pic but thats a ls1 pump with the billet spacer.

Or, you could go this route, https://ls1tech.com/forums/new-produ...-270-99-a.html

If you just want the spacer, bolt, washer and belt it would be $62.69 + shipping.

The picture you have is of a L92, not a LQ4, totally different problem. The issue is when you try to bolt on a LS1/LS6 manifold onto a LQ4 the TB will hit the upper radiator hose port on the water pump because it is shaped up and then curves out instead of just coming straight out of the pump like on the LS1 water pump.

Actually, the picture is a 5.3L with a LS2 intake!!! That was the worst case cenerio for fitment. The LS1/LS6 was way better for fit.

The pump is the new GM truck waterpump, and it is a direct fit for the older truck stuff, well, not sure about the upper hose, the waterneck is just off to the side.

depending on which tb, the cable will clear that new style w/p but not a dbw. you can use the ls1 water pump, all you have to do is use a puller to pull the pulley away from the w/p it self.

Excellent news, I think I have one of the new truck water pumps.
