You had compression because as long as the valves close low and don't open high, and had not gotten bent yet, you can actually end up with plenty, even too much, with a motor totally out of time and internally badly fuckered (as you found)
Other shop also assumed time was right because of compression or crank quality, and just went to the distributor.
Of course, you might mention to the customer that they want a real tear down or a different motor, if that one has mystery poorly installed performance parts sprinkled all throughout.

Good insight, I did discuss another motor with the customer. He wants me to try and save this one if possible. Worse case scenario I will probably sell him a used SR motor set.
I think if I clean the pan out real well, replace the oil pick up, and use all new timing components of quality along with a oil pump it should be okay.
I totally agree with your assumption regarding the shop that originally did the build/put the motor in. Based on the quality of work, its safe to assume they didn't know any better.
Although I will say it fired up easy and freely revved excellent considering my findings. One would think the valve overlap would have caused hard starting conditions. Even under load it was not awful in the low rpm.
Still find this to be astonishing.
