The option that I highly recommend for your application is our StreetPro 727A with the "Shortie Overdrive" option. This unit is only 7 1/4" longer than your 727 and is a direct bolt-in (other than driveshaft shortening).



What is this overdrive system? Is it a GearVendor product?

When I was building my '79 Dodge B+ motorhome I considered going to a 518 trans because my exsting trans was shot and I can get the 518 for less than a hundred bucks at the half price sales at the junkyard. I was looking at this type of conversion - http://www.transmissioncenter.net/SwapInformation.htm

Before I committed to it I asked around if this transmission would be a good choice for a motorhome (weighs 6500 pounds) and was told that the overdrive part would be too weak for this application. I ended up just building a standard 727. I would have liked the extra mileage. Now I have a new '74 camper which is around 7000 pounds and interested in overdrive again but this rig already has a good 727 in it and wonder if this shortie overdrive would work.
