    The new radiator I have has an outlet for a heater hose near the top of the radiator cap. Right now I have one hose to the intake and the other to one of the outlets on the water pump. The old radiator didn't have the radiator outlet but then again it was a 2 core and not meant for a BB chevy.

    Anyone??

    You can run it to the radiator if you want to. I think the rad hose is top of heater core but I could be backwards here. It doesn't much matter. If you want to plug the radiator outlet get yourself a peice of hose about 2 -3" long and a chuck of 5/8" rod or something similar and stick it in the end of the hose and clamp it.

    That's exactly what I have done for now, blocked it off. Just curious if anyone was using it for anything really.

    Thanks

    My BB runs the return line (the larger line on top form heater core) to the radiator. It has a plug in the water pump. I also have a line from intake to the water pump on my big block.

    My larger goes to radiator, then my smaller goes to the side of the intake, then one goes from intake to waterpump.
