I posted an ad on Craigslist looking for a Chevy 350. This is what I found for $250 bucks :) 65k miles on it when it was pulled from the mid 80's Chevy Suburban. We found a reman sticker on the engine, so it may have even less than 65k!
I'll use some engine cleaner to clean it, and then repaint the engine. Possibly install a Comp THUMPR cam, new lifters, and new valve springs. It came complete with Starter, Alternator, and Power Steering Pump!
