Stamey

Trying to figure out what my 99 2500 QC, SWB is worth. It has a newer design block since it had a cracked block under warranty. It also has a 2001.5 D70 with disk brakes and LS on rear, FASS, fire-ringed head, twin turbos and an Edge Comp. Stock injectors at this time. New VP44 in 2015. The transmission has billet input and output shafts, and a bunch of other upgrades, built by TRE diesel.
Truck as 146K on the odometer. It has a box to allow me to adjust the speedo for the tires and it has always been calibrated correctly. Paint on it is great. It has a little rust on inside of bottom of drivers door, but it has not spread to the outside.

I'm thinking of selling because I have had it for 16 years and am getting a 2006 now. What do you think it's worth?

Thanks,
Chris
