I don't know if this is a 911 emergency, but I need some advise. I have a 1997 Ram 3500 with the 12 valve cummins. The truck runs great just a little hot. I can get about 35 pounds of boost, but can easily hit 1200 on the pyro before leaving 4th gear. I got the truck used and most signs point to the fact that the previous owner knew nothing. The only number I can see on the fuel plate is 24242. Other than gauges and a south bend clutch I haven't done anything to this truck, but I don't want to buy an engine. Does this number mean anything? I'm would rather not find out its a "custom grind. " Thanks.
