OH yeah here is an easy way to figure out motor. 99% of the time this works. Some people say this is wrong. I have yet to see it proved wrong. All the 03 with the man tranny have the 305/555 motor. The auto's have three different power options 235/460 250/460 and the 305/555 motor. the 235/250 are known as the S.O motor (lower hp Cali emm) The 8th place in vin tells the story in the 03 a 6 in the 8th place has the S.O motor and if built before 1/03 has the 47re tranny. Built after 1/03 they have the new tranny 48re. A "c" in the 8th spot all came with the H.O 305/48re. In "04" model all trucks came with the 305/555 and have a "6" in the 8th spot. But all trucks built after 1/04 have a "c" in the 8th spot and came with the 325/600 motor. This motor is refered to as the 600 series motor. Lots of aurguements which is better. the 600 series can build power easier but can also drink down the fuel easier. The H.O just a little slower in stock form gets better fuel mileage.
Cheers

I'm sure... underscores the importance of checking the engine plate before considering a purchase. I assumed it was a 305/555 since it's a 48re. Fortunately for me, all can be remedied with a Smarty.

Thanks for the input. After work tonight I have an appointment set up to test drive the truck so wish me luck. I am apprehensive to buy based on the number of miles. I know it is a diesel and cummins at that but 114,000 is several miles. Anyway I will keep ya posted on what happens.
