trust me on this; your reputation regarding facts and knowledge makes it difficult for me to disagree.
i guess all im stating is that his angles could be better, much better. whether he will suffer from vibrations with 3.5+* angles is yet to be found. but, im just stating that he would be better pointing his pinion down ~3.5* which would lower both the front and rear WA's. it is a little more difficult than that, but a little math and a little time will dial in the perfect combo.
all my experience comes from my current chevelle. not only does my pinion sit higher than the tranny, but im running into clearance issues where the pinion passes through a crossmember. running the pinion down not only improves the clearance, but it was enough to dial in the numbers.
btw..... if hes not comfortable running the pinion down, he can raise the rear of the tranny to decrease its angle, and therefore decrease both WA's.
