I picked up a really clean one of these a month ago for cheap. It
was real high miles, 207,000. Its running great. The guy who had it
said they'd boiled some "carbon," out of the intake, not sure, or
somewhere, that was common problem on these and replaced the entire
spider[?] injection system. It runs hard and fast. Was there any
common problems with this early Vortec that anyone can advise about?
