Putting together a new 5.3L with all new parts. If the crank comes internally balanced and the rods and pistons all come in weight matched sets, do I need to pay a machine shop to balance my rotating assembly? Shouldn't it all be essentially balanced after I put it all together?

Thanks

The crank was balanced individually by the manufacturer. The pistons were weight matched by themselves by the manufacturer. The rods were weight matched by themselves by the manufacturer. If my rings weigh out as all the same why do I need to pay to have the rotating assembly balanced together as a unit?

You don't have to do anything but you have paid to get the whole rotating assembly weighing the same, why not calculate the Bob weight and make sure the assembly will be balanced..
