Eric's cam challenge

Go to ANY drag and drive event, sick week, drag week, no prep event, local bracket night, local oval track race, and walk through the pits, ask how many vizard engines or cams are being used. There are none. The guy doesn't build engines', he writes books. I have researched extensively to find proof of all his legendary testing, and cant find any. He also claims he was a race winner driver in some European small car deal, but I haven't seen any evidence that any of that happened either. The guy is the "OG snake oil salesman"
