The ones I saw today were ISX's, but I've seen a lot of Detroit 12.7's in the auction flyers, I think some C-15 Cats too. All big blocks 450 or more HP.
So how does a guy know if a truck has a low enough first? Look up the tranny specs and see what ratio first is?? Is there a certain total reduction (1st gearXaxle ratio) to look for? Or just drive one and see how slow 1st is? How slow (fast) should you be able to go in 1st?
