can I make a humble suggestion? since its not going to be origonal maybe you could consider a 205 rather than the 221.those 221's are getting hard to find and are valuable to restorers while the 205's are much stronger and quite common. that being said maybe consider a 4500 5 speed. up front costs would be more but long term costs would be much less and it could handle a blown motor better than a 420/465 combo with a 221.
