Thanks for the suggestions. I do have a 9 quart system; the 454 is a fat block with lots of water.

I can't do Scott's setup because of height restriction and a different water pump setup. I am thinking of a remote Canton expansion tank. If I plumb a line from my water neck adapter on top of my intake to the input fitting on the expansion tank and a line from the bottom of the tank to a port on the water pump, will I accomplish the same effect?

What cap pressure should I use on the remote tank?

Thanks,

Jim
