Hi Inliners,

I found this cool chart that calculates the RPM's of your vehicle @55MPH if you know your rear end ratio and rear tire diameter.
I checked my '40 against it at seems right.
My'40 has a 3:55 rear with 30" diameter rear tires. It states that I'm reving 2181 and my tach showed 2200 RPM. Enjoy the chart!

PS- If you are having trouble seeing the values, email me and I will email you the chart.

Maybe post this to the 'tech tips' page might show up better.
thanks

Here is an online tool to do same thing. http://www.thedirtforum.com/cgi-bin/milesperhourcheck.cgi
