I agree with F4Gary.  That would be my next thing to try.

Vette(s): 1979 C3 L82 383 cu in

My engine shop told me to check my water pump pully diameter when my 383 stroker was overheating. The pully diameter should be as close as possible to the crank pully diameter to get one to one RPM. Mine was much smaller and overdriving the water pump pushing the coolant too fast thru the radiator. I changed it out and temperature stays around 185-190 now.
