Your right on the car WP having the inlet facing forward, but I was told that the 07+ WP would work with this, and it's not looking like it will.

Looks like you will need either a new water pump or the truck throttle body

Thanks for the pics, I guess I'm just gonna get a new water pump. Do you know if I will have to have the truck pulley pressed on, or will the LS3 pump pulley line up?

You'll need an F-body pump with aluminum water pump spacers to run a DBW 90mm throttle body. The spacers can be found on Ebay. Don't forget 4 water pump gaskets and longer bolts.

Probably easiest to get the ls1 pump and spacers off ebay. I got mine from dirty dingo i believe with the spacers, gaskets and bolts for around 80 bucks.

just hearing 4 water pump gaskets and spacers and relocating pulleys, new water pumps sounds like alot of trouble to get this thing on there..... for no gains and loss in torque.... not trying to knock on yall at all, just saying.

Yeah its all for looks but it does look alot better than the truck intake. Plus gives you an excuse to get a meziere ls1 ewp.

But if i was to do it over again i'd get one of the edelbrock intakes instead.
