The final drive had been upgraded but he PO was not sure to what.

FInally got enough things right for a short high speed run- 70MP by GPS app was about 3100 on the tach (and the speedo was reading a little low)

So that comes to 3.7 with 225/75 tires

That seems a bit excessive.

I'm thinking for a 23 footer not towing anything heavy 3.21 or 3.55 might be a better option.

A lot of my travel involves I95 in the South, lots of flat cruising.

What's the point of having a 70's muscle car if you can't enjoy 70's freeway cruising?
