If RM, Nyes, Musi, etc. had shops in Canada, it would be an easy choice for me. I would send it out to one of them to be refreshed. My big problem is I have to trust someone elses word on who is good.
There is one guy who was recommended to me. He builds the engines for Ashley Bart's blown alcohol dragster. I would think he could do a good job of putting my engine together.
