From the number of views I'm going to guess the answer is no.
The EV-27 comes on around 1-1.5k which seems kind of a waste to me as when riding I don't drop it lower than 2k.
From the numbers the S&S 510 should come on around 1800-2k which seems like a better idea to me.
Less wasted power band.

You're reading too much into what the marketting puff says! Far wiser to ignore all cam marketting and go by other riders' experience. The EV27 is so popular because it can be all things to all men - even Tina! You won't notice when it 'comes' in, because it gives such a smooth ride. Perhaps you don't ride below 2k because your current cam won't go there?!

I was looking for something to make the powerband take a small step to the right on the scale.

Question....Any one have a formula to convert the numbers from .020" lift to .053 lift. Or is that something only the cam designer can measure?

I did cam design and geometry at college (a long time ago!) and would say that only knowing the geometry of the cam profile on each lobe will allow us to do that. So yes, probably only in the gift of the cam designer.
