    M20 performance block honest opinion needed

    my sons M20 block cracked and was dumping coolant through the crack mixing with oil. For financial reasons and time constraints we swapped in a stock M20 motor.
    His built 2.75 stroker block was originally built a while ago by SDP Euro in San Diego and then rebuilt in 2016 also by SDP Euro



    The block has Wiseco pistons with total seal rings, from 2016 new rod / main bearings, 272 degree Schrick camshaft, adjustable cam gear, ARP head studs.
    Even with the crack in the block the motor still had full compression on all cylinders and was tested by JMP Autowerkz in Canoga Park.


    Now we would like to sell the block and head for all the parts that are in it but we have no idea what fair an honest price would be.
    The block is done but all the internals are good and the head is good as well.


    thanks for any feedback

    I'm not the guy to tell you what they're worth but whatever that number is, they would be worth more if they werent part of a dead block that no one will want to pay to ship.

      sell the head separately, sell the head studs separately.

      the rotating assembly is difficult to sell - anyone building a motor will want to use new rod/main bearings, and machine shops will not usually do a bore to match used pistons, so if the pistons are a custom oversize they are not worth much. used rings are worth $0 as well.

        I would feel decent paying maybe $600 for an 885 head with a 272 and the cam gear if it was skimmed and checked out by a machine shop, and otherwise ready to drop onto a motor.

          The bore is 0.080

          Thanks for the reply.
          TBH The heads have not been checked by a machine shop but had perfect compression 2 weeks ago.

            The block cracked? Very unusual, it's usually the head, under the cam between cylinders 4-6.
