Just my two cents, I just did a swap on my 03. I search high and low for a used engine. Almost bought a entire used truck for the parts, but every test my mechanic used. Made my search come up short. The best used engine I could get was 1800 with less then. 100,000. My enigine went out at 106,000. So It didn't make sense to me to pull the trigger. Finally found this place http://accurateengines.com/remanufac...dge/47-engine/
. To be honest, I was ready to give up and move to the other side. My mechanic went back and forth checking with the company. He convinced me to go ahead a purchase this remanfactured for 1900 This still may be my last ram, but I must admit it runs like a beast! Added a better oil pump and a torque converter, it will be my sons in a couple of years. Never again will I go down this road. I thinks it worth looking into. Talking to my mechanic and Tom from accurate engines they knew everything that is wrong with the engine, I just wanted the truck to run. That It does!
