Bill, you have too much time in your hands digging out skeletons...
The "D" dart is not the only car that has been built for SS applications only and not Stock.
I have a copy of the complete Chrysler data package submitted and approved by NHRA buried somewhere at home. They built 50 cars. Headers built by Jr Headers; the Holley carb has the same specs as the race Hemi carb. The intake manifold is a cast iron single plane intake as used in 273/318 marine engine applications. Solid lifter cam 0.520" lift made by Racer Brown and domed pistons. 4.88 rear end gears, stick shift only car.
