Terry,
If all this doesn't elimiinate your vibration then I am ready to......well you want to bring the car to Pentwater?
#!- forget about the horizon! Sorry for any confusion there.
#2- When the car is as you indicate
#3- assuming your floor is reasonably level- lay a level on the flattest/straightest top part of the door. Pay very close attention to the lay of the bubble. A degree wheel would be great..
#-4 Set your motor as close as you can to the level measurement you just got from taking the level of the body, I.E.; say the body is all set and it is sitting level.
#5- the motor should be level, if necessary a degree or two with the back pointing down is ok.
#6 Install the driveshaft, it should lay in a straight line, NOT necessarily level and probably wont be. Now measure the angle of the driveshaft with a short level or a degree wheel.
#7 It is from this point you can check you pinion angle, it should AT THE MOST be level or now straight from the drive shaft.
Never UP. Trying to explain this is hard on the internet.....Lets say your engine is pointing down a degree or two, transmission of course will be the same with the drivehaft following the same line. Here comes the pinion... lets say you have a pretty hot motor and typically good rear tires all resulting in decent torque and HP. This is where you will want the pinion to go below the tranny tailshaft from DOWN 1-1/2 degrees to a max. of DOWN 3-1/2 degrees. From what I am reading about your driveline I think you would get by with a NEG. 2.
If you end up with wheel hop, which I doubt very much, drop the pinion DOWN a half degree unitl the wheel hop is gone.
This make sense to you?
Whish I wasn't on dial-up, I am only a couple of days of setting Cpteddies. I certainly will now take a full set of photo's on what I do. I already posted getting his motor in left and right as well as front to back with a down angle of .01. I need to get his driveshaft set up and photographed, and then adjusting the pinion angle.
