Hey Doug, this subject has been beaten to death, do a 'search' for pinion angle. You will find a ton of info, drawings and diagrams from a number of sources. Read them and you'll be able to make your own decision on what is best for your car and why.
The search function is in upper right corner, just below the 'new member' section. Good luck, oj

 

You want the engine/tranny centerline to be within 1 degree of the pinion centerline, and parrallel. The next important check is to make sure the WORKING angle of the commonally used single U-joint is 1-2 degrees, and not to exceed 3 degrees. (This is NOT the same as the engine/tranny/pinion angle). All measurements should be taken with the suspension at ride height.

thanks guys. after i posted my question i talked to a mechanic at the local chev. dealership and he said the same thing. my engine sits at 3 degrees so he said 3 degrees up on pinion will work ok...
