You will get a kick out of this Dan, this is CSX2005 engine as it looks today, I doubt the -5 on the valve covers? I know engines were haphazard in their allocation. I am pretty sure none of the Hugus cars got the XPH engines, and I think neither did Tasca. Hugus said he supplied only complete cars to Tasca? That would screw up all the matching numbers!
