I would add this friendly observation. I think the Barton's have christened themselves as a Mopar engine building shop. One just has to look at their web page: http://raybarton.com/ and look under "engines" and "customers" to substantiate it. I am not at all arguing that they aren't excellent engine builders for other brands, but I think it is safe to say that their specialty is Mopar. Personally, I believe they are the preeminent Mopar race engine shop in the country. There are none better with the II and III generation Hemis.
