Dave, the owner, runs the website Mopar Style. Might want to mosey on over there and contact him. They had an engine in a magazine contest a few years back, but failed to finish because of bad parts. This was when they were first launching Diamond Back engines. It hurt them, but it was out of their control. It was not their fault. He seems like a very congenial, knowledgable person, and will talk to you directly. He races Mopars, and his daughter was even featured one time in Hemmings Muscle Machines for her racing efforts. He is a a genuine Mopar guy. Seems to know his stuff. He is a Texan. That means you can probably count on his word, more than any other state. They don't take their word lightly down South. It's an honor and a tradition. They tend to back up what they say.
