Like others have said. It depends on your particular combo, and the funds available. A lot of builders are known for this motor or that motor. I personally have had great experiences with Blair Patrick, Tony Bischoff and Jimmy Kuntz. There's nothing that comes out of any of these shops that's not top notch. I would say Tony would probably be the most versatile based on the different engine combinations he's won the Engine Masters Challenge with and that he has competing currently.
