Like mentioned before, get the machine work done first. Local shop charges $10 Dip, $15 resurface block, $10-20 per cylinder hone depending on damage, $20 line hone crankshaft journals, $20 to spin the crankshaft. Around $150 if there is nothing major, and the machinist doesn't have to do too much mechanic work.
