Not sure what you could have done during your 30 foot test drive to a stop sign. However, no telling what occurred during the repair shop's test drive.
If the shop isn't showing any signs of contrition, I would take the engine to an independent shop for a forensics inspection and written report. You could show this to your engine builder and/or an attorney.
It sounds like a rod nut wasn't tightened to spec, but that's just my guess. If detonation was the cause, there should be signs in the combustion chamber and the affected piston/cylinder (e.g. melted/deformed material).
Sorry to hear that.
