Classic/Antique Car Repair: 51 chevy, hemmings motor news, volt conversion

Question
I recently purchased a 51 Chevy 1/2 ton with the original motor and 3 speed, running but rough, new battery but hard to start and even after running it is hard to start.  Body is pretty straight, some rust in the usual areas.  For the time being I would just enjoy a good starting and running truck.  The general opinion around here is that I should scrap the motor and put in a small block for reliability and access to parts.   

What are my options?  Thank you.

Answer
I am not a fan of the "drop in a small block to solve your problems" group. A small block is no more reliable than the 216 CID engine that was standard in your truck unless you are prepared to go to the extent of the complete computer controlled fuel injected version with the 700R4 computer controlled transmission. then you will also need to change the rear end and the rear suspension as well as a complete 12 volt conversion. Then the reliability factor has credibility. I just did a run through my new issue of Hemmings Motor News, the old car hobby's bible for parts and accessories, and found dozens of sources for parts for the old stove bolt six, in fact just about any part that you want for your truck. So that puts an end to myth number two. The problem with your engine could be as simple as a carburetor rebuild or the installation of a new set of ignition points. I would do a compression test on the engine, that will tell you the condition of the inside, and then a complete tune up including a valve adjustment and see how it runs. Also I hate to see an old vehicle in pretty good condition altered from stock and lost as a true antique. If the engine compression test shows the engine in poor condition then you need to sit down and decide which way to go, but use your noodle, not just rely of "what some guy said".
