I have several big block transmission cores if you want to have one to rebuild. Some are 727 A's and some are 727 B's. I need to clean out my garage. To me - each one represents 47.5 lbs. of top grade aluminum so that is how I would price them + shipping & boxing if you're interested. I live in northern Kentucky about 50 miles south of Cincinnati, Ohio to give you a reference point shipping wise.
