Is This Possible?

High lift and limited duration with a wider LSA is the way to up the breathing (with the lift) without hurting the low RPM cylinder pressures, which makes torque; a lot of overlap that comes with long duration and narrow LSA hurts low RPM cylinder pressures. So yes, the Whiplash is set up for that.

Look at any of the 'torque' cams and you will see them setup that same way. And in the early 70's, when the Arab oil embargo doubled and trpiepd gas prices almost overnight, everyone was making cams like this for better mileage while retaining some performance.

Yep, check all clearances because the Whiplash takes the lift pretty far for stock valvetrains; check for coil bind and for retainer clearance to the valve stem seal and the guide. Using a lower lift in the .450" range is safe, but leaves something on the table in terms of performance.
