All -
I have an 1971 Demon with a 318/904. I just put a 8 3/4 with 3:91's so the speedo is a bit off. I would like to put the proper or as close to proper gear in to bring it back into spec's. Can someone point me in the right direction.

Thanks - Charles

 

What size tires are on it ??

 

If you do a little searching, I posted up the chart and calculations to find the answer.

Look here.
