I have a centersection/chunk out of my 8" to bring to a friend at the Pensacola show this weekend. He's been looking for a 3.00 to add to his fastback.
Efforts to determine the gear ratio when the chunk was in the car were in vain, and there is no tag on the chunk.
I'm told that the number of teeth on the ring gear divided by the number of teeth on the pinion gear that will give me the approximate ratio. Is this true and an accurate measure?

Thanks - Dickson

Yep. That's the way to do it. Just count the teeth on the ring and pinion and divide. That will get you the ratio.

Remember: divide the Big number(ring) by the little number (pinion)
sorry,I couldn't help myself.

Thanks for the reminder!!!!

My first car was so slow off the line that something tells me the gear ratio might have been "point something" - the little number divided by the big number!! Thanks - Dickson

And to think that I've been doing it wrong all these years. *LOL*
