They came behind v8s also. There was a loaded 67 CST here with 327/3spd/OD. That was a great highway cruiser. I never got to check the rear ratio.
I am working on a 67 GMC 250/6 with complete original OD. It is running a 3:92 rear ratio in a dana 44. I haven't got to the OD yet, but it is not engaging. LivRat was down and gave me some ideas on items to check in the electronics. He also has some tips on putting this OD unit behind a 4spd.
I sold a complete unit on here a couple years ago. I wonder if it was ever installed and working?
