I'm not line boring an engine, thats just how much it costs. everyone says its expensive, but no one has given me the actual cost. So I am sharing the info. you may have gotten all that work done for $500, but how much for line boring? and it should be $100-$150 is a guess, I called several machine shops including one of the recognized premier engine builders,and that is how much it costs if you live in seattle. I will have $500 into the crank alone when I am done, although most of that work was done by crower cams, I had them drill a 216 crank for oil, grind the crank, and tap a hole in the snout, plus shipping, Crower cams is a pretty reputable company as far as I know
