balanced and blue printed means the rotating parts are balanced so when it is running there is minimal vibration(you can usually run it at a higher than normal rpm or HP without damaging it.)
Blue printing just means he took measurements and recorded that; when he rebuilt it.
(example: bore sizes,,bearing clearances,...)
If it was a race engine it could go as far as matching the combustion chamber sizes,intake flow ,exhaust flow by grinding away and smoothing parts.
My 600xcsp eats fuel too,,things that helped were loosening the track off to double the
book value,,keeping the exhaust valves clean and synthetic grease and oil.
