just did a th350 swap
i just pulled out my 5 speed and swapped in a th350
conversion. used the swap kit and long tail shaft so i can re-use my stock drive shaft. i also bought and installed a spohn adjustable torque arm..... adjusted the shifter and also adjusted the torque arm to a neg. 3 deg pinion angle.... anything over 40 mph i have a vibration through my whole car.....do you think maybe the drive shaft needs to be re balanced or do i possibly not have enough neg. pinion angle ???? my friend says maybe neg.6 or neg. 8 degrees ??
its a 2001 ss camaro that has the 2 inch drop springs all the way around.
thanks for any help.
mark.
