I visited their operation on Democrat Rd in Memphis a few times in their early years....looked like a few Berco grinders and some other older machine tools. Advertising has done a lot for them.

I will say this. When I was shopping for a cam a few years back, I was calling them every week or so. And got a different recommendation from every cam "tech." Next time it will be a call to Racer Brown probably, and just have a cam ground for my engine.
