It is off-set to the passenger side about 3/4". Is the best way to move the engine over the same amount (which creates some other space problems for me); or **** the engine in the frame ever so slightly? Does anyone know how the folks at GM handles this problem? Not having the engine square in the frame is my best solution.
Having the pinion shaft offset is quite normal and to be expected. A Ford 9" has about 1 1/4" offset.
You do NOT have to install the engine off to one side. This is sometimes done (even from the factory) for steering clearance, NOT to align the driveshaft.
You should avoid canting the engine. This will definitely cause premature failure of the u-joints.
The correct alignment is for the engine crankshaft centerline and the centerline of the pinion shaft to be parallel to each other. This is when looking from the side and/or from above.
