Pinion Angle Help needed
Hey All,
Need some help/clarification on next steps for setting the pinion angle on my 71 Demon. Car had a 904 transmission, which was swapped out for a 727 after the 904 got destroyed. with the 727 being a couple inches longer i had to get a new driveshaft. I also installed a new rear transmission mount which changed the motor tranny angle.
With the new transmission I got a driveline vibration above 40 MPH.
Current setup is the motor is angled down 1.9 degrees (at harmonic balancer), rear of tranny shows angled down at 2.1 degrees, driveshaft (at front behind yoke) shows angled up at 1.6 degrees, driveshaft (at rear ahead of yoke) shows angled up at 2.0 degrees. Differential yoke shows angled up at 2.8 degrees using a 4 degree pinion angle shim.
What are your thoughts on the above setup and any changes that need to happen to eliminate the vibration ?
Thanks in advance
Mike
