about how much does it cost to go .030 over on a 350 motor?

Are you talking just machine work? Whole bottom end? Balanced? Thats a very open question, so I'll try, around hear average runs about $100 for a bore and hone. Best of luck,

i would say when it's all said and done your looking at 1400-1800, for good parts and good machine work, a nice complete job- no corners cut smile.gif

Had my 327 bored .030", including hot tanking, cam bearings, honing, rods reconditioned, crank polished, reciprocating assembly balanced, freeze plugs installed, for $600.
