It states if you're looking down from above, and your drive shaft is crooked (mine would be right?) Then your putting added stress on components. So this is where I really started getting confused

But if I understand you guys correctly then I should not be worrying about changing my pinion offset it will be just fine where it is for a BBC, right?
With using correct mounts and trans crossmember of course

That is correct, your driveshaft will be straight in the horizontal plane. (My understanding) When it is all bolted in you will then have to set your pinion angle in the vertical plane with angle shims. In vertical plane, it is said to be bad to have the driveshaft straight in line. To my understanding it is best to have a 2* down on one end (usually transmission output) and 2* up on the other. (usually axle pinion) There should be others that will chime in with more or better info !

Thanks a lot and for those pictures, seeing the examples makes it much easier to understand (for me anyway.)

Angle should be no less than three degrees and no more than five degrees for maximum universal life and minimal power loss to universal flexing. It can be perfectly flat the way racers do it but the universal will burn up in hours to days of use as the bearings in the universal are not turning. The steeper he angle the more the bearings roll but it cost energy to roll them and the pressure in the joint increases as it flexes (why a raised truck breaks universal joints so often that they carry several spares in the cab).

I wish I would've recorded all my angles before pulling the motor/trans, just out of curiosity and as a base reference, didn't think of it I'll remember for next time
