Just saw this thread. Wasn't sure why you painted your '71 truck engine GM blue instead of Chevy orange? Mine came factory blue in '78 so I'm just keeping it that color for restoration, but I always liked the orange better (looks less like a Chrysler or Ford). I think Integrated-Jay told me first year for blue inline sixes was '78, and probably last year was '81 after which they went to black.
