I know I asked the same question when I put my motor in also. I was told the angle of the pinion and drive shaft should be no more than 3 deg, pinion being lower, this will cover any twist in the axle on start up from stops. For the engine I did like Eric did. I put a SBC 350 in my '46 1/2 ton Panel and set a small bullet level on the intake/carb mount and set it level. Thats how I was told to do it and it worked out great.
