I didnt see where you said you have talked to a local engine builder/machinest??? Are you going to attempt a rebuild whith no help from a shop? If so, I think based on your posts so far that this would be an un-wise decision. Unless you have more engine expierence than what you have displayed here I think you are looking to spend a lot of money and may well run into trouble, I mean your first post states clearly that you didn't even know that chrysler produced a 400 or what BB stood for. You should contact a local shop so that you at least get the basics covered. Doing a stroker motor is not your basic overhaul and will require a little machine work and some fine measuring and detail work to do it right. But it IS a good way to go with the 400 blocks. Just my thoughts :)
