hughes whiplash cam and other cam opinions

I'd install that Crower cam wherever THEY tell you it should be installed in your combo. Honestly, without prior experience with a specific cam/combo or a dyno where you can play around with advancing and retarding a cam, you're really shooting in the dark and hoping for the best. Not saying advancing and retarding is a bad idea, but I'm not really big on guessing. I like to see the black and white.
