sounds about right my 72 350/th400 is about 2500 to 3000 when going 60 to 80 then goes up to 3000 to 3300 at 90 to 110

Kinda depends on what you mean. With your size tire (255/60/15) a 1:1 top gear and 3.55 rear would give you 56.9 mph at 2500 engine rpm. However, 3000 rpm should move you 20% faster, so at 3000, you should be moving at 68.3 mph.
