B body water pump on mine. Just the radiator hose connections and water pump connections nothing to cap off.

Nice! Are you running the B body accessories and brackets as well?

No, using f body bracket and accessories.

JD was it you that's running the B Body water pump? I thought about running either B or Y body pump cause there is no oil cooler line. To minimize having to cap things off. Wasnt sure if that would create an issue with accessories lining up.

I have a spare b body water pump on the shelf but the fittings on it were not a perfect match (direction wise) for the molded heater hoses from the Z28. So i kept the Z water pump and removed the hose nipple for the oil cooler, threaded the hole 1/2” npt and screwed a plug in.

You guys and your silly heater core fittings.

Love the swaps guys. Those that are running heater cores - are you using the restrictor valve on the supply (to heater core) line? Did anyone drill a small hole in their t stat?

I have been reading in various places the lt1 pump can do some funny things (airlock) when t stat closed.

No problems with the cooling system or heater system.
No mods in the factory temp tstat.
I don't recall if I'm using the factory restrictor. Both cars are covered in snow. I'll check my pics.

Hey baker7888, what are you using for power steering pump?

No restrictor or modified thermostat on mine
