Engine builders...this machining cost sound excessive?

I know my work took longer, and was more expensive then I thought it should have been, but looking back, it was only a few hundred dollars extra. He did some work that he did not clear with me first, but I know it is done right and worth the piece of mind going forward. It's getting harder to find a good shop, especially one that knows Mopars. A lot of these shops are one, or two man shows, and many owners are getting up there in years. At some point I think we will see them disappear to only have the option of big rebuilders available. Then you will get what they tell you, with no option for custom work.
