Getting nervous about cost of engine rebuild.

I don't know how mechanically inclined you are but you could possibly assemble the engine yourself.

I’ve done one motor by myself completely and I have tag teamed many. I am confident in my ability to put an engine together. It just usually takes me a while to do it by myself and this is a very reputable shop so I thought I would give it a try. They will also be putting the engine on their dyno so I figured why not let them handle the whole thing so if the engine has issues on the dyno there will be no disagreement.
