Reply to "double water pumps."

thanks, guys once again.
just to clarify.
i am in the end stages of a complete nuts and bolts restoration.
full engine rerebuild of a 4 bolt main quenched steel headed 351C. the engine builder has a rep as one of the best in our region.new ross racong pistons, SS one piece valves and roller rockers.
we have a new waterpump with bypass, the under car tube are brand new stainless, new fluridyne radiator from Bob Byres and sucker fans to match.
taking a vent tube from top of radator to back of car, the intenion is to the pressure tank, (new stainless pressure and expansion tanks) thoughts on the location of the vent tube running from front to rear. and who has done this.
since im going to a hugh amount of trouble with this build i dont think andother 2 or 3 dollars will killme to put the electric water pump in also if it is a good and worthwhile mod.

am just in need of the robershaw 333 thermostat so if there is a spare one out there or is there a Stant equivilant. Also has anyone heard of stewart components they do components for race cars and seem to do mode to robershaw thermostats.
