'97 K1500, "S" (to be converted hopefully), 3.73's, 147k miles and counting, from what I can tell bone stock, but not for long!
'73 K5 Blazer, original motor (never been out of the truck), new cam and Holley replaced the Rochester at some point. Dad baught the truck from original owner with less than 30k miles. Future plan is to restore the body (again) and swap in computer, harness, motor and trans from the above and add one ton axles and springs (long way out i'm sure)
