I am the second owner of a 1965 Econoline truck. Several years ago my Dad and myself restored this truck as well as rebuilt the engine. I am wanting to do a few upgrades such as a fuel injection conversion. I am pretty sure by all my research that I will have to change the head/intake to make this happen. I need some advise/input in this matter. I looked into the v-8 changeout but I would like to keep the dog box uncut. Thanks for any direction available in advance.
