Last year I had my 440 short block and heads redone, .30 over, crank polished, everything magna-fluxed, new bearings, new pistons, rings, new valves, hardened seats, etc., total price $2000. I did the final assembly, basically installed the cam, heads and manifold. That would have cost another $250 if the machine shop did it. I might have spent another $500 for the parts including cam, timing chain, oil pump, water pump all stock. So my stock 440 rebuild was just under $3k with a little elbow grease on my part. $5500 for a stock rebuild seems a bit over the top to me, just my .02 cents.
