Thanks for the feedback everyone. You've provided good links that I can use for further education on this. My original plan was to put a 292 engine in the '46 truck, but a friend of mine showed up the other day with a '67 Chev truck with a vortec v8. It sounded like as much time was spent trying to figure out how to make all the modern electronics work as was spent turning wrenches. So now I will do my further research...
