67 Dart 270...Project Old School
After watching all the coverage of the 2014 Power Tour, I am beginning to think that might be a fun goal for my 67 Dart. I don't think it would be fun to drive 1500 miles with a 3.91 gear turning 3500-3700 RPM. After looking at the postings on this site about installing a 43RH OD trans in a Duster, I decided to try the same thing with my Dart. Over the weekend I picked up a core:
The trans looks a mile long and weights a ton even without a converter. I am trying to decide what converter to source to match up with the deeper first gear in the 42RH. The factory high stall is listed at 1600 RPM. The 9.5" converter I have in front of my 904 foot brakes to 3500 RPM. I would like to be around 2800 stall with the new converter, but it seems that anything above about 2600 RPM requires a custom built converter ($$$) versus modified stock units. I was always told the more you hack on the stock converters to raise the stall the less efficient they become. With there being a lockup in this converter, I am not sure if this is a real issue when cruising down the highway.
