Hello all.. I'm new here but I need some advice. I just purchased a 1956 4 door buick special, but I am wondering if I should modernize it, or keep it the way it is. The engine and transmission are fine, but if I were to replace them with a modern engine, does anyone have any suggestions on what type I should use for both the engine and transmission. I'm trying to find one that would be compatible with the current drive train set up, or else that could be a pain. One thing I would like to do though, even if th engine stays the same, is to modernize the brakes. Does anyone by chance know of a modern system that would work so that I could put front disc brakes on the car. Replacing other parts is not a problem, but I am at a loss for what size rotors would fit, as well as the other brake parts. Thanks to all who read this, I really need the advice. I have only worked on modern cars/show cars, and working on a project like this just leaves me at a loss. Once again, thanks a million. SV
