This is exactly what I just did.

I'm guessing you have a lbz since your sig says your cracked a piston awhile back? If so what was wrong with your factory water pump which made you install this Danville pump?

No lly. Busted a welded one on the gear side and didn't want to go through that again replacing cam gear, since it wore the teeth out on it while sitting inside motor.

I installed one on a customers truck last year while doing head gaskets. It failed a week later and mark covered it with no issues. Stuff happens.

I know he will take care of me, it's just the 6 month warranty that concerns me. Only frustrating part is races are in a week! Lol

Unless your spinning 4500 plus rpm I don't see the need for pinned or welded myself. My opinion of course.

I had a welded pump on my built motor.

I raped the stock pump for 190k with tons of 4000+ rpm runs on the stock pump and no issues with mine, my LMM has had a few 4000+ hits and no problem.

well when you have to replace it three times for the same reason you will.

It's the curse off the LLY, jebadiah put a curse on them after his LB7 lost to one.

Yes, unfortunately we can't control the out sourcing that ACDelco and many of the other big name OE manufactures are doing these days so it definitely has an impact on things. There isn't much I can say about it other than we will get it taken care of. We have only had a handful of them fail out of the hundreds that are in the field doing there job. The issues with the waterpumps is they are just like turbos except the water pump is mechanically hooked to the motor so there is no give. Waterpump pressure measured in the housing right before the oil cooler pipe attachment ranges from 1-2psi at idle all the way up to 90+psi at 4700rpms and when the trany shifts or you chop the throttle all that pressure wants back out. Pretty harsh place for them to live in and makes it that much worse when the manufacture cuts corners to save a buck or two.

Technically yes but the pressure is what helps with the cooling process so if you remove it then you will lose some of it. I don't know where the crossover is between the two.
