OK, next time it's a slow day at the office call, do not email, some of the well known FE builders on this forum, the
332-428 Ford FE Engine Forum forum or that have been recommended to you, and tell them
"I'm building a 427SC Cobra from ERA, how hard is it to find an original iron 427 or 428 block and then, roughly, what will it cost me for you to build, meaning all the machining, parts, stroked and bored and with only high quality parts." Everyone but blykins and barry r. will be low balling you on their guess, so keep that in mind. If they say,
"well, you have to bring me the block" then keep looking. Buying a used 427/428 block is fraught with peril.
