You ever see a road test with the bicycle wheel attached to the car? That is what they use for their information not the speedometer. Problem #1: The 120 mph speedo did not have a tachometer option with it. Have a photo?

It is certainly possible to peg a 120mph speedo & exceed that MPH, the RPM & rear gears would determine the top speed along with other factors.

I'll tell you right now, with 3:55 gears there is NO WAY an AAR will do 137. Maybe 125 tops. Might be able to do 137 with 3:23 gears. Trust me, I know what the top end is on a 1970 340 Cuda with 3:55's! No Man With A Good Car Needs To Be Justified

That being said, classic industries makes a tach that will fill the empty hole where the clock would go. http://www.classicindustries.com/product/mopar/e-body-challenger/parts/me1316.html Last edited by MoparMike1974; 05/26/17 12:14 AM.

However, the technical authority here will not let my Cuda get street legal until i have this issue fixed (typically German behaviour). Since i have to adapt mph to kmh just with tape stripes for 30, 50 and 100 kmh, my idea is to get a 39 teeth speedo pinion and remove the existing with this. I have 3.55 gears and 245/60 15 rear tires. Last edited by Knillse; 05/26/17 05:29 AM.

I have no idea why. Means when I drive 120 km/h the speedo shows 120mph. When I understand the pinion tables and tire calculators correctly, I have to use a 39 teeth pinion to cover the complete mph range with my 120 mph instrument.
