Is it true if the eight number in the vin on a 04 2500 is a 2 then that means it has the lly motor in it. i looking at a 04 2500 crew cab and it has a 260000 and am just curious about that particular motor as in the goods and bads, also if 260,000 is to much as far as doing mild mods on like exhaust and intake and possibly tuner. I have tried reading on the lly's but not sure if this truck will have that motor or the lb7. PLEASE help totally new to the diesel world and really want this truck. thanks to all who replies

on the llys they made the injectors eaiser to change. (you dont have to pull the valve cover). i dont think thats to many miles. i have seen them with alot more than that on them. common problems are injector wiring harness at #2 and #7 injectors.. (easy fix) also a wiring harness that will rub by the alternator. Good chance both these issues are already fixed on that truck. also look into getting a lbz turbo mouthpiece as the factory one is a restriction
