I look at it this way. If I wanted a Keith Black engine for next year my order would be in for one right now. You then will get a call from Ken or an employee to go over your build. At that time you send in a partial payment. While waiting you save up the rest of the money to pay it off. Come Spring you receive a FINISHED block and not one needing to go to a machine shop to have finished. Just my thoughts and it worked for me when I stepped up to the best big block Mopar engine block produced.
