Dave,
Hi, I run a C-6 from GER [precision converters] in PA,USA.
Very good pro street,dual stage valve body with a matching 2,800 stall converter. I have over 20,000 HARD miles on this baby,would recomend them !
The C-6 is 33" long, so I only have a 8" driveshaft, a AOD is 30 " long. Art Carr can build one for you,but it's 2 times the price because he cuts off the AOD bellhousing and installs a SFI bellhousing to fit a 460 big block and you have to run one of their custom converters to work.
Good luck,
Perry.
