The next phase of the build came after Powerdriven diesel saw our first pass at the drag strip and asked if there was anyway we could fit a dodge 47rh transmission in the box truck. We quickly remembered we had two cores sitting around waiting for rebuilds and with a little trading we managed to get a Powerdriven 650hp Transmission. Part of the deal was also that we had to meet them halfway at the 2016 NHRDA world finals in Ennis Texas to do the trade. Will also convinced us to bring lil Debbie with us and do a novelty pass and the burnout contest so without hesitation we loaded up lil Debbie and hit the road. We had a great time in Texas meeting both Todd and Will for the first time and watching the Junker Drag Truck battle to the finals in the 10.90 class where he very narrowly lost by breaking out something like .03 of a second more than his competitor. Unfortunately because of the televised event and the schedule running behind the novelty pass and the burn out contest were a bust... Maybe next year.

Lil Debbie in tow

Once back home in GA we began figuring out how we were going to make this tranny work in lil Debbie. Luckily Powerdriven was also able to hook us up with DPC (Diesel Performance Converters) which is not to far from us here in GA. Phil Taylor hooked us up with a triple disc torque converter that has worked flawlessly for us. To make the 47rh work we used a Dodge 12v adapter plate and starter. Unfortunately the adapter plate we pulled off our parts truck (chicken truck) was cracked and worn down pretty good. After some (6hrs) of attempting to tig weld the cast aluminum adapter plate we finally had something that was fused together enough to be acceptable. We then bolted everything up and used the dodge transmission rear mount and fabricated a small bracket to work with the existing cross member. With the trans all mounted the only thing left to do was shorten the drive shaft a little and get a shifter. With a little help from a B&M pro ratchet shifter kit and a local drive line shop we were up and running with our new #lildebbie racing transmission. We also went ahead and put some cheap 60lb valve springs in it.

Welded adapter plate

Of course at this point the only thing left to was to take her to the drag strip and see what she would do. once again amused but reluctantly the let us on the track. This time we were able to improve to a 17.07 ET at which would be almost 5 seconds faster just from the auto swap. At this point we were pretty pleased with how the 8000lb bread truck was doing so we decided to take it to the local truck pull and see what kind of numbers we could get out of it. With the crowd gathered round we laid down a whopping 235hp and 553lb which was actually more than we expected. The crowd loved the show and we were very pleased with our set up. At this point some "difficult" decisions needed to be made. Do we take it out and do our conversion as planned or build it more and see just how fast we can make the newly popular #lildebbie.
