i've heard it was due to the influence of new speed limits instituted back in the 80's (70's?). But yeah it's very annoying. Brother's Performance will recalibrate and reface your speedometer for 170 mph for $40 or $50... I'm picking up mine today It's gonna be nice to know how fast i'm going w/o having to figure out the speed from the RPMs...

it was illegal to sell a vehicle with a speedo over 85, course Ford got around that byoffering the 140mph speedo as an 'accesory' in their Ford Motorsports catalog
