question about 66 dart

wow....is Ray Ryder still there?
He has to be over 70 by now.

I had his help in building my D Dart.
One change I haven't seen written about is that the D Dart had all of its pistons reversed from one bank to the other, thus off setting the offset, and reducing friction that was used for cold start piston slap noise reduction. This made a huge difference in performance.
