Pinion angle

Maybe a better question is, "do you know" what you are looking for? Ignore the driveshaft, the angle you want is between the crank centerline (transmission shaft) and the pinion. Figures I've see around here recommend starting out about 2 1/2* down at the pinion with the car properly setting on ground. That is again, down from the crank centerline, not ref. to ground.
