3.09 gear set with 3.23's

Try and figure out why it's vibrating.

Driveline? wrong balancer or torque converter weighting?

The rpm drop from 3.08 1st to 2nd's 1.90's is the noticable torque affector. It will loose some 'charge'...might bug you after a while.

1st and 2nd gear there is Zero vibration all the way to 6500.

vibration happens in 3rd above say 3600-4000.

3.23 gears 100+ mph. Fixed

if you’ve got a driveshaft you want to send me that doesn’t vibrate I’ll gladly try it.
