Like I'd mentioned.......that was with a leaf spring car, and it does have slicks, and it does make close to 600HP, and I does launch like I stole it......and I doesn't want the driveshaft to smack the floor pan when I do........been there, done that.....
The thing you're forgetting is that a LOT of places recommend 6 to 7* pinion angle with a leaf spring car that's making some poop, and my car would not work doing it that way.............that's all I'm saying........
I'll face the firing squad with ya Big I've kept my mouth shut while this subject has been debated here, but for 25+ years I've done it your way and never had a problem. For a leaf spring car, I line up the driveshaft with the pinion, then push the nose of the pinion down around 5 degrees. I just leave the u-bolts loose and push the rear end where I want it, then weld the perches.
Theory-craft and books are nice, but what works in practical application in the field and what the book says don't always jibe.
