Pinion Angle Opinions Needed

[mongocanfly]

as long as your angles are really close to the same it (should) be ok..think lifted 4x4..they usually have big angle numbers...3deg is what most try to acheive ...id try it and see what happens...you just dont want excessive angles as it causes u-joints to bind more..
i understand the diff angle changing while lowering...but why is your trans angle that much...did you set it that way ? to match rear? (ok ...just re-read and see your up against floorboard)
the IH truck im working on was 9deg from the factory, but i changed it to 3deg..

The rear end is 6 degrees so the least I can go is 5 degrees on the motor then...would like to get close get closer to this than the 7 degrees I have now. We are putting in new cab supports and shims to see if I can get closer to 6 or 5. The firewall would be fairly significant surgery at this point since the bellhousing is what is hitting first.
