i am doing a heads and cam swap, i am replacing the following things:

PRC 5.3 heads stage 2.5 w/EHT .675 springs
LSR cam 227/235 .614/.624 113 LSA
TSP ported LS6 oil pump
LS2 timing chain
LS7 lifters
LS2 lifter trays
MLS .040 head gaskets
all necessary gaskets and bolts will be replaced

i am wondering if i should be changing my water pump as well during all these changes? i have 130,000+ miles on my LS1, have great compression and regular maintenance...just need to know if i should change the water pump with a stock replacement.

If it was me, I would defiantly change it. Also did you have your heads milled?

no did not mill them, oh and they are 5.3's not LS6...i will fix it. i plan on making just under 11:1 compression with the 62cc heads and .040 head gaskets

It more of a preventive measure kinda of thing. Hell I'm replacing mine in the next few days after my head and cam swap, and im only at 55k.

So you want to be a G? Meziere Electric Water Pump with a 630.00 price tag lol. Stock replacement is fine I think.

yea i dont need an electric one, a belt driven one is fine, my budget is what will be best for my car, so saving money is good, but i dont want some off brand crap.

i will just look at it and check it out when i remove it, is there any signs i can look for when i remove it to see if it is failing or should be replaced, vise from it leaking and all, what other sign will be present if it needs to be replaced? cause it runs fine now
