I try to pick up ls cranks for less than $100, usually $80 or so. So for $250 you are getting bearings. If the bearings are aftermarket then $250 is high. If the bearings are oem then the price is right but in order to correctly order the oem bearings you need to reference the block, crank, and rods for colors and then plastigauge to chek to see if they are in spec.
