1975 Cheyenne Project

[Dyoungblood]

I just got a 75 Cheyenne with a 350 someone put in at least 20 years ago. It's been sitting for almost 15 years out in a field but apparently the motor was strong back then and built by a professional. I'm trying to decide if I should tear this thing apart and try reusing the parts after inspection and rebuild or if I should just try and make it run with new rubber, fluids and a carb. The only thing I can tell about it without pulling it is it's got an Edelbrock Torker, some long block, and a Rochester QuadraJet 17053507, some small headers and a bunch of wasps nests.. the motor cant have more than 30000 miles on it but its been in the elements for a long time. Any advice or "if I were you's"?
