Anybody ever do a chassis and/or engine dyno run with their 28' chevys? I've seen a few Model T and Model A dyno runs but never any old chevs, curious how they would compare.

Good question.
I have not, but the next time I take one of my trucks to visit the local high school auto shop, I'll have this done.
This will probably not happen until sometime in the fall.
Cheers, Dean

My experience with chassis dyno’s is that you cannot reliably compare results among multiple dyno’s.
They are not directly reading torque and speed like an engine dyno. They try to measure the rate that a car accelerates the drum and then integrate those numbers to measure torque. Major variables among them is how well the tires actually drive the drum, the mass/resistance of the drum, and the sampling rate (frequency that drum speed readings are taken).
We often had trouble correlating our results from different days even though we used the same dynamometer and even the same set of tires each session.
