Don't know how much you have into the truck already but to rebuild that 216 boat anchor will cost a few bucks. Even the cost to rebuild a 235 or newer 250 is more than a compariable V8. The 12V conversion is a definate though if you want to add anything electrical to the truck.
Your decision should be based on how you plan to use the truck and how much you want to throw into it which you will not get back out when you sell it. Don't base it on our suggestions as you are the one paying for it and driving it.
From your previous posts and the pics it sounds to me like it may be better to sell what you have and get a newer more complete truck. Have you sat down and figured up the cost of everything you want to do to it? The end result may be enough to justify going another way.
