91' 5.7l 350. Water pump needs replacement and I can't seem to find much information on which is recommended. Currently deciding between acdelco, duralast, or gates. I've read Delco uses the lowest bidder. Haven't heard much about duralast and can't find much of anything about gates other than all of their parts being on eBay.

(Not sure if this post is in the right section)

I got a Murray for my '98 K1500-marked "assembled in USA from foreign and domestic parts" so far no problems.$50

I got the "heavy duty" option from advance auto parts for about $40 works great. I think it has a thicker casting and better impeller.

Just make sure you get the right one. some motors with serp belts run a reverse rotation pump.
