Hughes Whiplash Camshaft

Has anyone used one of their cams? It's a hydraulic flat tappet for small block apps...The video of the guy's 340 sounds damn good with the 340/360 cam....Post says 8.5 comp 340 not to much more other than that...If you never seen it check they website Hughes Engines.....Again I was wonderin has anyone else heard/used/or kno of someone that used one....I was thinkin of usin one in my 318....
