The information regarding the final drive ratio on the Revcon is sketchy.

In one place i read that it is stock Toronado. But when i look into what that number might be i get different answers.

Also, mine is a 72 which makes it unclear what generation Tornado they used. It may have been sourced much earlier.

My calculation watching the tach and measuring the tires makes it close to 4.10 but that seems doubtful.

More likely is my tach and/or speedometer are not accurate.

Do i have the math right?

engine RPM at 60 equals 5280/tire circumference X final drive ratio ??

So, how much trouble is it to unbolt something and count the teeth?

Thanks
