According to Bentley's data 3000 RPM should be 75.3 MPH on an A type and
78.3 MPH on a J type. I presume many of us have close, but no cigar, tire
sizes that will induce some variation. Roger Elliot's data is very similar.
He said 25.3 for the A type whereas Bently sez 25.1 MPH per 1k RPM.

T/R 3, @ 2400, I'm doing 67 MPH, @ 3000, 76 MPH, very seldom ever go above
that. On our trip to VTR 99, Dan Masters & I averaged 72 MPH, until Vermont
& the mountains and we were always at the 3000 RPM.
