I'm in the place, it depends on where you shop around. Don't spend too much on the stock block, you can get one brand new ready to assemble for under $400, DSS sells the bored and notched ready for the stroker for around $700, a sportsman for the $800 range, and the R and Dart for under $2,000. I say this because I know a guy who paid a machine shop $1800 to fully prep his stock block for a 331, not assemble, just machine and install cam berrings and freeze plugs.
