Build your own engines, or have them built?

I have done it both ways on all big three brands in the past, but I have found an engine builder 10 miles from my house that will do all assembly for a little more money and he will warranty it for 1 year unconditonally. It really makes more sense to me if you are trying to achieve a certain compression ratio or you need additional machining milling of the heads that will require more trips to the machine shop.

I am an industrial mechanic by trade and know how to turn a wrench, but this just makes more sense to me, because I am helping support a local small business with a great reputation and it frees up more time to do other things on the dart.
