Truckguy- if your motor is stock, then it should be a 5.3 liter, not a 5.7....even the 2000 model Hoes (with the exception of the Limiteds) had gone down to the 5.3

If yours is really a 5.7, then maybe somehow it was a special upgrade option offered at the time, because there may have been some leftover 350s?

motor size

according to the vin ( letter R in the 8 place from the right end of the vin) and logos on the motor its a 5.7

See what engine your truck came with by the VIN number. This might not mean anything if your engine was swapped out at some point.
