Meziere Electric water pump appears to bolt right up the LS7 with one minor mod! I tried fitting up my Meziere WP319 LS1/6 electric water pump to the LS7 since when I called Meziere they had no idea if it would fit 
It does fit with a minor interference at the passenger side lower bolt location of intake manifold where the throttle body bolts up. I clearanced the lower portion of the intake manifold in this area about 1/8" and it bolts right up!
I noticed that the bosses on the LS7 waterpump are about 0.070" closer to the block than the Meziere so I will have to shim this to ensure correct spacing on the belt tensioner.
I've enclosed a couple of pic's where you can see the circled red area for interference and the difference in the bosses.
Great to know that there is another free 6-8 RWHP is just waiting in the wings on this motor!
