Driveshaft Angles
Tremec has an awesome angle calculator for donload to cell phone. Use phone body to lay against engine/trans/pinion.
Also does rpm/speed and something else that I've forgotten.
Alwhite00.....I'm confused that you would post this question when you are about to tear it apart and install 9". Dimensions are gonna change.
4.9 degrees down on the trans is WAY TOO MUCH.....you've spent $30k on the car already, moving the engine/trans for a few hundred bucks has gotta be done at the same time as the 9".
Driveshaft should enter the pinion 3* down (177* across top and 183* under the bottom) because the axle winds up about that much at launch and it should end up straight under load so as not to pull the u-joint apart.
Actually 5* for bushed arms or leaf springs and 3* for rod ends.
Do what DriveShaft Shop says for cv or u-joint.
Andrewb70 and Interceptor5588 have good advice.
Jim.
