Thread: to many angles!

Tweet

First, set the body up at the angle it will be when the car is finished and on the road, level, down in front, down in rear, whatever. Once you have the body attitude like you want it, install the motor with the carb pad level. This will normally equate to about a 3 degree down-bubble on your angle finder when faced off a crank pulley or transmission output shaft (less yoke). Install the rearend with the pinion at a 1-2 degree up-bubble. This will leave 1 or 2 degrees for the pinion to climb the ring gear under cruising power and result in a 0 differential of angle between the crankshaft centerline and the pinion centerline as viewed from the side of the vehicle. When measuring for driveshaft length, have the car sitting on its tires with the suspension weighted. Easiest way is to put it on a drive-on lift, even though you will have to push it on by hand. That way, you can get underneath to measure the length of shaft you need. You should have the transmission yoke available and the pinion yoke installed on the pinion. Push the trans yoke into the trans as far as it will go, then pull it back out 5/8" to 3/4". Now, measure from the centerline of the trans yoke to the centerline of the pinion yoke. That is the measurement you will give the shop in order to make your shaft from scratch.
