The old 350 in my 77 K10 rust bucket died. So i bought a complete used Goodwrench 350 motor off craigslist really cheap. It is supposed to be a running motor with low miles out of a RV that has been sitting in a garage for over a year. I have it on a stand in my garage waiting for above freezing weather to swap it into my truck. Before I drop it in an 'hope for the best', what should I do to it besides clean it up? I'd love to tear into it but I don't have the money to do it up right so I want to drop it in with as little work as possible. I will of course change the oil, etc. What is the minimum I should do before I install it and give it a shot?
I know this engine was a gamble but for what I paid it was a small gamble.
Thanks,
