Pinion angle

[fakessturbo]

Thank you gentlemen.

I cut the control arm mounts off today and I am fabing new ones, shooting for 2 degrees down on pinion, shimming the trans +1 degree. It also makes the carb more level.

My understanding of pinion angle is the it should be the opposite of the transmission angle. The line continuing from each should be parallel. So if the trans is +2 degrees, the rear should be -2 degrees if the installed height in the vehicle of both parts are the same.

The question is what is the maximum angle I can point the pinion downward?

that is correct.....5% max....less the better


thats 2.5+2.5
