Speedometer Off By 10mph - Muncie Tranny Fix

Bigger rear tires on the 1968 Camaro equipped with a Muncie 4 speed transmission slowed the mechanical RPM speedometer down by 10mph. Here's a fix.

Thanks for the vid.

I wonder what gear ratio you have and how tall is your tire. Just for reference

[@revivingretro]

I'm going by memory here
Rear Tires P295/50R/15
Rear Axle ratio 3.55
Pink drive gear
Brown driven gear got me really close to actual (maybe around 1mi mph off)

Thank you for your reply. Great video it was helpful. I removed the bullet peice and looked inside the output shaft inside has no gear on it . I am trying to figure out what I need 🤔
