First, I'm new here and I have very little knowledge about building a performance car motor. I've searched the internet looking for info on finding the difference between the 305 and 350 crankshaft and spent 2 hours and haven't yet to find anyone who seems to truly know. I can't imagine this not being an ancient question but all I can find is that they are different, but no one seems to know how to tell which one is which. I have a crankshaft on my workbench but I'm not sure if its a 305 or a 350, but I know its one or the other. I don't have both to compare to each other either. Does anyone know the distinction between them? How can I tell which crankshaft I have?
