Classic/Antique Car Repair: 69 Corvette Overheating, radiator system, stock exhaust


Question
I have a 69 Corvette with a 350 Engine bored to 30K,
with 11 to 1 popup pistons, heads shaved 30K, with newly installed Air Conditioner and it runs hot (215-220 degrees). Please tell me what I can do to reduce the temperature.  Is my stock exhaust the problem?

Answer
Exhaust could be one factor.

With all the modifications you have made to the engine, have you upgraded the radiator system to the new C.I.D. rating of the engine? Did the car have factory air? If not, the radiator was rated so and did not have a condensing coil in front of it.

Also is all of the flaring in place? Some Corvettes need the air channeled just right to operate efficiently.
