Engine builders...this machining cost sound excessive?

The cost of the work performed is reasonable. If you install new pistons the rotating assembly should be balanced IMO. 65'

i paid $1250 for hot tank clean up, a bore and hone ''supposedly w/ a torque plate,( supplied the new pistons for measurement) , new cam bearings honed to fit , (had to supply the cam for fitment), zero decked , and freeze plugs installed '' by the same machine shop that does a some of street outlaws stuff.
Got a good friend that works there now , wish he would have been there back then tho.
rotating assem. was race balanced by hughs engines , smooth as a cats ***!
