My 216 cannot be heard at 40mph (over the wind noise and engine fan noise :))
On reconsideration, I can't hear much of anything above 40mph in my '53!
I can't differentiate anything between noises on the video, but a 216 does have a nice smooth ticking sound when running. Even 235s will have some noise with solid lifters, but not as loud as the 216. As mentioned, if you have hydraulic lifters, you shouldn't have any noise beyond starting and warmup.
At first all I could see was the temp gauge at 212, which I think was used in the 216 years (through '53). Didn't it change to 220 when the 235's were introduced? Late in the video you can see the oil pressure gauge at 30 max, which would indicate a 216 also.
Those are the reasons I asked about the engine size.
When was the last time you pulled the valve cover and took a peak at the valve train and adjusted?
