Lineslinger has a good and valid point. I also use a local engine builder, who by the way is awesome............with bowtie products. But FE's are a little quirky, and he admits it. So, I choose to use a dedicated "Ford Racing" engine builder.
Just my opinion, but for a basic rebuild yep, any competent shop can do the job. But, I feel, if you want a product that has endured trial and error durability plus the benefit of dyno-testing to maximize performance, go with a specialist: KC, George Anderson, etc.
