around my area, machine shops (the few that are left) are so backed up, it took me a week just to get a set of rods reconditioned. One shop said they weren"t even taking any more work in for a month.
I've had it take weeks before, but on average its 3-5 days for the bottom end machining and another week for the heads.
I have a few motors and many sets and singles of heads in the machine shop at any given time.
