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

I would do all the things listed above just to have a good starting point. Also if it has a cat converter then it will have an 02 sensor. These are cheap ($25) and will kill performance if old so replace it no matter what.
The thing is, 1977 was not a good year for engine emissions equipment and performance. I don't think you have a lock-up TC.
Even Corvettes only had about 180 HP (and terrible fuel efficiency) and you'll have much less than that. It may be that 60 is about all it can do under the best of circumstances.
