It depends. a balance job can run upwards of 4-5 hundred bucks or more. Mine was 350, using stock rods and forged pistons. add that to the 75 bucks I paid for the crank, plus the 500 for the pistons, 150 for the rings, 100 for the rod bolts, another 75 for the rod bearings and you're at the cost of a stroker kit that comes already balanced.
