My truck sat since '96 and it smoked a lot when we ran it the first few times, but now it doesn't. The 350 that my Granddad put in it probably has over 300K miles, and you can hear it. It's got a wrist pin knock.........not good. It's kinda weird that mine doesn't smoke much even though it sat longer than yours did. The engine in yours just might need a teardown and rebuild.
