Instant overheating

I have an instant overheating problem and I hope some of you may have some ideas on what to look for, and how to fix it..
First, some history that may answer some of your initial questions.
I have a truck radiator (4 rows of tubes) on my coupe.I had the top tank removed and had all the tubes rodded out.I have a B waterpump on the engine which has the larger impeller.The waterpump shaft has very little end play.
I have a four blade fan and a temperature gauge with the sensor on the pump.After running for about 5 minutes, the gauge reads 140 degrees, and the top of the radiator shell has condensation on the outside from the heat.
I also had the engine totally overhauled by sleeving back to standard with new pistons, pins, valves, etc.Could a "tight" engine cause excessive heat?Can't really tell if this is so, as my coupe is 12 volt negative ground, so the starter is a little aggressive.
The timing appears good, as the engine starts "right now", idles nice and acellerates well.I'm also using a Model B distributor that has the "flying weights" which eliminates the manual spark control.
Your thoughts?
Regards..
