      Go to Mortec.com
      They should all be there, fairly comprehensive.

      3691959 Car & truck 73-90. Could be either a two bolt or four bolt main.

      336781 Oval port open chamber 73-85. A good casting that will flow well when tweaked.

      Overall, a nice foundation for building a big block with some mild to serious HP.
