Considering that these cars were designed and built when the national speed limit was 55 MPH, how many of you regularly drive your stock, original Maverick/Comet at today’s interstate highway speeds? My Comet has the stock 250 c.i. six and 2.70 rear gear. It seems happy enough at 55 mph and just around 2,200 RPM but I wonder about a long road trip and sustained speeds upward of 70-75 MPH to keep pace with modern traffic. Any thoughts? What have been your experiences?
