A 77 Winnie Minnie (Chevy) will not go more than 60 mph. Converter lockup? I don't know where to start without obd. Thanks

There was a device that could be installed on older vehicles that prevented the vehicle from exceeding a certain speed. It's called a 'governor.' They were deliberately installed on U-haul trucks to prevent going over 55 mph. I know, I rented a couple back in the middle '70's. When the maximum speed limit on interstates switched from 70 to 55 mph for a few years, people started putting "governors" on their engines so they deliberately could not speed any faster. It sounds like your vehicle has one of these installed.
See if you can locate an old-timer mechanic ... someone who was around in the middle 70's and I'm sure they will be able to tell you exactly where this is located and how to remove it. I just remember, they were a real pain in the neck. I rented a U-haul truck (I think the year was 1977 and drove it over I-40 - Black Mountain - Ashville, NC). I thought I'd never make it up that hill because that darn governor would not let the engine rpm where it need to. And even down-shifting did not let the RPM's get high enough. I barely made it over the mountain. Oh, I remember well. I bet that's your problem!
