Driven the '37 with a stock 216 on a highway 180 mile round trip with ambient temperatures at about 95+ degrees and dew point about 60 degrees. The morning drive was pleasant but by the return in the afternoon we were really glad to see the garage door. Normal engine heat and noise added to the other factors, plus wind, wind noise etc. made for a memorable and fun experience. The wife was a good sport...but she did ask if we could add A/C.
I'd do again, but in cooler, less windy weather.
