I agree John, I called back and informed them I can get a rebuilt short block for $1699 and free freight from <!-- w --><a class="postlink" href="http://www.farmerlink.com">www.farmerlink.com</a><!-- w -->.  They are refiguring the estimate.  (Apparently $1000 per cylinder is a standard for the larger tractors)  I may just order that rebuilt block, put new seats and new valves and should be in for around $3000-$3500.  I also am thinking of upgading to a 1655 283ci, I heard it is a direct replacement, have you heard or know that?
