Bill-----I always took pride in knowing almost as much about the competition as about the DDA engines.............and Allison transmissions , when I was a salesman .

The Super 250 was a long stroke 250, had a 6.5" stroke instead of 6" , and gave it something like 927 cubes instead of 855 .

I still maintain a competative engine library .
