Molded Heater Hose Delete. Inlet/Outlet Jumper Hose

Any of you guys jump across the inlet/outlet and delete the water going to the heater core? If so you got a part number?
Oh Yeah, it's a 350....

Thanks!

A short piece of hose does the job fine.

Just plug the holes with a fitting. There is already a by pass in the water pump via the hole below the bottom bolt. Just takes a tad longer to purge the air out. Most people jump with a hose b'cuz they can't get the fittings out or are just doing a temporary thing

No, you'll need something with a tapered pipe thread.
The threaded holes in the intake & pump where the hose nipples go are 1/2" NPT.
