Whiplash cam. Your thoughts

Been looking at several cams since I need to rebuild my 340.
My 340 duster has rpm air gap, 2800 stall, 2.02 J heads, 3.91 gears. Gonna be bored .30over.
Has anyone used a whiplash cam from hughes.
This cam is on my shortlist


Sounds clips please if any of your guys have some
