I would worried that the heat from welding would be hurting the seals ? Maybe ? I'm I off base here?

I expect you'll find being properly balanced plays a bigger part then most would think.
The water pump and the engine.

I'm with THEFIRM here, I installed an LBZ on my LLY simply because of failure frequency whether stock or built the LBZ's last longer, plus the pumps better capacity and lighter impeller are a plus. my .02

I understand how a rotating assembly is balanced, but how do you balance the water pump?
If it's zero balanced at the factory, adding weld, pinning, keywaying, etc must all throw it off balance...
Will the LBZ bolt right in place of a LLY pump without modification? I need to change my pump currently.

Well we tried about all the fixes available up until the end of last year and went to an electric pump. End of problem. Another nice thing is you can keep the pump on and circulate the water when you are between passes on the strip and help cool it much quicker.:thumb:
Just had to modify one of the top mount hole locations on the pump (cut and drill only) and heat and lube up the LLY radiator hose to install on the larger inlet and that was it. So far so good!
Electric is the go for race only applications for sure.
my stock pump lasted a month at 710 hp, the chance of it failing away from home, and not being an easy side of the road swap led me to go straight for the electric. year and a half later still going strong with no issues. i was all set with trial and error that i've already seen dustin and a few others go through
So you are saying you lunched the OE LBZ pump?
The "customized" pump that Tony did for me is on and held up all day with my thrashing.
In the 11th hr I made a major breakthrough with my tuning so wil luck I won't cross 4,000rpm much if at all.
Things are finally starting to come together...
Yeah, I wish I had another chance to hit the track, but I guess that's what the dyno is for.
Yeah u have dyno in your shop still dont you? Are you running twins or single charger for the challenge?
No John, never tried that, had welded and keyed and both failed, electric seems to work well. My understanding uses less HP as well.
Love my electric pump....wouldn't trade it for anything. I did drill my tstats and I run a 30psi cap now too. I run my truck without any fans on most of the time now, and it has stayed below 210 water temp and oil temps go to 220 only on wot runs
Im not sure if your saying going electric is only for racing , but I have electric on my truck and have driven it everyday for the last 5 months with out one issue .
