[AT] Cummins 250 Information

[James Yost]

Correct me if I am wrong but when you talk Cummins 250
that meant the HP not the cubic inches. If you think
about it Chevy had the 250 c.i. 6 cylinder. Cummins
were rated in HP as I remember. 

These engines were ran some in our semi's where I
worked years ago and we had very little problem.

Thanks, Jim
