should i part it--84 K5

[jerry moss]

well after pulling the intake and having the EGR passage cleaned out it still isn't close to passing california emissions. i'm tired of working on it and thinking of parting it out. it runs great but appearantly has bad valve guides and carbon buildup on the pistons,NOX numbers are "gross polluter" high. here's some details: 84 K5 blazer, p-s, p-b, a-c, tilt, cruise, p-w, p-l, "sequoia package" whatever that is, 4 inch lift, 15 x 10 alcoas, nearly new 33s, no rust , just a few minor dings.
should i junk it or try selling as is ? my g/f owns it and she paid 2 grand for it 4 years ago but doesn't want to put more money into it.
