=====================================================================
I mostly have had the 3:23's myself also. It is a good street ratio and 
I raced it. But now I want to get a bit radical and use the 3:91's. I've 
had them before too. My 3000 stall converter feels way too loose with 
the 2:76's. Kinda like the centrifical clucthes on go carts. Sloppy and 
barely moves at first but then it grabs and goes.
