And, this covers only US cars. Canadian and export cars would have metric speedometers so would be different.
My 77 olds cutlass supreme brougham definitely had a 85 mph speedo . I guess gm though of the sporty camaro as a preformance car ( and still had hopes of 100 mph + speeds ) My friend had a 77 Monza mirage and it had the 305 V8 4 speed and definitely had a 85er . We had the 305 out within a year and a L79 / Muncie in it . We almost had the speedo back to "0" again once .flowjoe said:Interesting. I could swear my old '77 El Camino had the 85MPH speedo. I also seem to recall other late '70s cars I've driven having the 85 limit...I must be getting old.
