There are no new Koleno or Mopar blocks. Marty Koleno died. Expect to pay $3500 for a used one. If you can find one. For a new block Indy aluminum is the only game in town. KB is producing blocks again but $7000. Not sure how quick to get one. If you're interested in a used motor I have friend with a -1 headed 540.
