I really am not interested in anything with OD



Just curious why? There's a lot of sled pullers and drag racers that seem to abuse the 47RH/RE's, and 48RE's without many issues. If you Google the Cummins powered Lil' Red Express truck you'll see that it's running consistent mid 10's with a best of 10.38 and is using a 47RH.
