I personally don't put any mechanical part on my car that says Autozone or Duralast.
Set that one aside as a spare. A new engine is a PRIME opportunity to put a good pump on.

true but it depends what viewpoint youre coming from i speak of long term performance on a built/boosted motor thats a daily driver if youre not doing that to your ride than by all means get the Acdelco but nnext time i do my water pump it will be a meziere electric unit takes care of all that cavitation problem and takes a load of the crankshaft freeing up some power at mid to high RPM

Both my L67 OEM water pumps exceeded 125,000 miles. Neither failed, but were replaced just because I was in there. And I've been building and thrashing my 93 for 5 years.
The electric unit frees up a LITTLE off the crank, but further loads your alternator, which further loads the crank.
Want the compromise? 5 or 10% underdrive WP pulley. The electric WP isn't worth the cost when you compare it to the minimal hp gain you get.
