Default Unicorn truck water pump?

Anyone know what engine this style pump came off of? I've installed an LS1 intake on a 5.3. But now the TB won't clear the standard WP. From what I've seen this pump will clear. But I can't seem to find it. Any suggestions? I'd like to get the 3 bolt DBW TB on there as it's what I have.




It look's like an LS2 pump, but has truck spacing.

I think it's easier to just use ICT Billet water pump spacers, Then you have several pumps to choose from and they are already tapped for your steam line.
