I'm glad your in possession of a classic American made truck from the '40's. Unless you have a ton of money to throw into this project by incorporating a V8 engine and all it's related custom drive train accessories and custom mounts etc, then good for you and your effort. However, I would suggest that you remain very conservative and find the engine of the period for your '46. It would be a much easier restoration and I believe end up becoming more valuable from a historic view point. Just my opinion....
