Many classic Newells in this era (late 70's to '90) have mostly Detroit Diesels, and if your rig was 38',or less with no tag axle, it was probably a 6V92. I know, however, Tom's 1990 is under 40' and has an 8V92 (no tag). There are a few that came with Cummins, but I believe that was a special order from buyer.
