A silly question : my tank has a cap and its connected by a large hose to the w/p and a smaller hose to the radiator side, its the stock for the '71 BB, is this a over-flow or expansion tank?

Update
So far, there doesn't seem to be any effect by anything. However, the weather has been cooler and the problem less pronounced. So I think I'll convince him to wait until December and sell it up north.

My 2 cents.... I had the same problem about 2 years ago when I installed the 383 stroker. Alot of stuff was replaced but I didn't think about having anything done to the original radiator. It always ran around 200 until I had it recored and added 160 thermostat. Now it runs around 175-180 on normal summer days and 190 on when it's very hot. 165 during the winter. Nice and cool.

You can also eliminate the air pressure problem by drilling a very small hole (1/16) in the thermostat "plate". This doesn't seem to affect engine temps but does release unwanted pressure.
