whining rear

I have a 742 case 3.23's out of a car I drove and they were quiet. I might throw that in before Carlisle. My plan was to buy a carrier for the 8.75 swap in my Scamp and run them until I pulled the 3.91's from my Road Runner and installed a SG in the 742 3.23's to put back in the Road Runner.

Unfortunatley, these 741 3.55's are whining......:banghead:

More work.......lol
