Welcome to the Ford Barn. This site is dedicated to stock / restored Fords, with a high level of understanding for period modifications. We are probably going to be helpful with questions about the stock 1940 Ford, like the body and interior. Other websites are probably going to be more helpful when it gets around to the street rodding side of things, like the HAMB (the Ford Barn's sister site that is dedicated to vintage hot rods; many of us belong to both but are much more active on one or the other). Neither site will probably have much expertise on modern pro-street modifications, but you can probably find that help on another site. The internet is a big place, I have confidence that between the various communities you will get your questions answered.
