My 305 is dying. I've found a guy who's willing to sell me a 350 that came out of a 1979 pickup. Its pulled out and everything, he said it got to hot and seized up on him, wouldn't start or something. I don't really know the whole story. It sounds like I can pick it up for $75 bucks. But my question is can I rebuild it. If it seized up on him does that mean the pistons melted to the block or what? What can/can't be done? So my question for all the experts. How do I know if this engine can be rebuilt??? I'm going to look at it tomorrow morning, what should I look for to make sure its okay? I'd like to rebuild it and replace my dying 305 with it. What should I be looking for??? Any advice is very welcome. That includes rebuild advice, for example what cam should I use, where could I get a good low cost rebuild kit. Keep in mind my blazer is mostly a daily driver with a little off-road action so I want to build the 350 for the best fuel economy/perfomance possible.
