Would you use that drive shaft to Pinion on My production car???

73 A body Sport. 440 installed in a SB K frame 1" higher then a normal BB K frame. 76 rear axel with the soft rubber axel mounts removed bolted to stock 73 springs.


What Pinion angle between the two should I be looking for.????
550 HP, If, that matters.

SET, MY Pinion angle Mike!!

Yes I would.. assuming you run leafs I would set it at
about 5*-6*
EDIT
Now days its easy to check with a Go-Pro to see if
you need more or less.. but if your getting more than
that I would look for springs... also something that
most dont think of is when you dump off the gas.. that
rear goes nose down a lot so if you have a pile of pinion
angle that goes the other way on decel

Sport 440 I left the Trans at 4 and brought the pinion up to 2

It seems pretty obvious that the guys running factory drive lines with minor mods will only need to worry about the pinion end. More modified to off the wall combos where the engine/trans angle has changed, or the rear axle height has been changed a lot, then It would be important to look at both ends. A Pro car or well built chassis is for the most part would be set with the trans pointing at the pinion( I would assume?) so just going off the driveshaft to pinion would work well. There is a fairly wide range you can get away with on pinion angle, my guess is 3 to 4 degrees either side of correct at full power. That thought comes from the way SS springs are set, and how far off they are when not under power.
This is my interpretation of why there is so much argument over which way is right.
