you might be thinking of Steve Dulcich. it was on an episode of engine masters with a big block mopar (440, i think) and he was musing about it and mentioned the comp "thumpr" line and cams of that nature.
anyway, can confirm that those types of cams can make power. my "low compression" 400 will attest to that. however, all the parts need to work together to get it there. otherwise, they function much like a band aid and sound cool. which is fine if that's what you want and just want to melt a credit card and grab something off the shelf.
