Richard--
THANKS! That was what I was looking for! I run a 535 cid BBF w/ 3.56 gears with a locked differential. I was looking to go to a shorter gear for drag racing--like a 4.11 or so, but didn't want to give up highway pleasure. I think the T56 will take the abuse (it handles the Viper pretty well) and the .5 6th gear would give outstanding cruise mileage (2.06 gears!) not to mention scary top end. I am sure that ultimate top speed would come in 4th or 5th considering aerodynamics, but it's worth a try. I have a contact to BW in process now. Nice to know they already know how to spool up an adapter for me. Which box did you decide on--I know they make a few different configurations. Again, thanks to all!
