1987 20th Anniv IROC SPEEDO Question
I have a 1987 20th anniv IROC. I was wondering if it was common that the speedo tops out at 85 MPH? Seems unusual, but I really dont know. any help is appreciated. Philip

The speedo that originally came in it tops out at 145 MPH. Tack Redlines at 5500 RPM. Anything else means that it was replaced with the wrong parts.
