Hey JAR41,

Tell us about your speedometer conversation. Which gear ratio rear end do you have in that beauty?

I had a local sign man make this decal on his computer. It is clear with new numbers and marks.
I replaced the 4:11 R&P with a 3:54 from a '54 Chevy Powerglide. Gene Schneider was a tremendous help on this conversion. He told me the change would result in a 14% change in speed. I calculted the speeds and you see the results.
I dont have to calculate my speed all the time. As you can tell by the difference in slow and faster speed it would be difficult to calculate that in you head all the time. I think this is an original idea. I don't have it patented so feel free to use it.

That is definitely cool, Jim. It seems like you had mentioned it someplace before. But the old "a picture is worth a thousand words" comes into play again. Frankly, I was kinda wondering how it would look. No more, IT LOOKS GREAT!!

Nice, creative idea!!
