*** I found this info over on Pro-Touring.com and thought it would be useful over here. This may make it easier to keep your stock radiator during a swap...

This is the water pump for the 2010+ L99 Camaro (#19207665). It uses the same accessory spacing as the truck motors:

You will also need the tensioner as well. found the PN on Rockauto... ACDELCO Part # 12628025

good to know...

There is a company called LS Brackets that sells on eBay and their own site that sells relocation brackets to be used with that idler.

I'm going a different route because of the dual quads I can use this: http://www.summitracing.com/parts/edl-8895/media/images Its kind of pricey but the electric pumps are double that price and more.

That might be the inch I am looking for !!!
What is the difference in pumps lengths?

Does the 2010 Camaro pump need the dirty dingo spacers?

I see the tensioner is that all that is needed?

Will the tensioner that you list still be needed with a dirty ding upper A/C bracket?

About 1/4" maybe 3/8" at the most (the Camaro pump being the shorter of the two). The angle of the picture makes it look like more than it is.

No, the Gen 5 Camaros have VVT. So, the water pumps are spaced out pretty far to clear the timing cover. The belt spacing is the same as the Gen III/IV truck engines.

Yes. The thermostat and water neck comes with the pump. There is money to be saved by buying an LS1 'vette tensioner. They're about $40 cheaper than the Camaro one and it will bolt right up.

Thanks, I was hoping for at least a inch, but at this stage 1/4+ will help, I have the dirty dingo A/C mount and you say I will need the Corvette tensioner, (a second one?)

I have the L99 water pump on a 4.8 that I'm building right now. I measured it and a spare truck pump that I have and verified for sure that there is 1/4" difference in "height". The shaft of the L99 pump protrudes through the middle of the pulley about 1/8" so you could grind that off to get the last possible bit of clearance. But, keep in mind that the water outlet on the L99 pump points straight forward and is sticks out about the same distance as the pump shaft. The radiator hose is going to be furthest thing from the block. In other words, if whatever you're trying to create clearance for is also in the way of the water pump outlet, the L99 may still give you some fitment problems with the hose outlet.

My comment about the tensioner really wasn't in regards to the DD A/C mount. I just meant that the L99 pump doesn't come with a tensioner and the LS1 corvette tensioner will fit it (and the 'vette tensioner is about $40 cheaper). I have no experience with the DD mount.

Thanks, I wonder how much I can cut off the snout and still hold it to the shaft, it is pressed on, right?
The 5.3 is going in a 46 Chevy pick up

I know this is kinda old thread but does this water pump outlet clear the stock 5.3 alternator bracket looks like it might hit?

The water outlet on the L99 pump does hit the alternator bracket on the part that holds the idler pulley. Most folks are using the L99 pump on a truck engine are switching to a car intake. So, they are relocating the idler anyway because it interferes with the throttle body.

Here's a picture that I stole off ls1tech that shows what I'm talking about. Note the relocated idler:
