I got called one time on a 1940 Chevy sedan with the 216 and it would overheat almost before you could get out of the drive. It would start, but then sounded like it was laboring to run. Found out the owner had decided to reset the timing at the distributor and had it wayyyy slow. I turned the dizzy back to where it should be and no more heating issues.
Does it have plenty of power going down the road? Is it a little hard to start in the mornings? Does it "ping" when accelerating?
