Yeah, you'll need more cam because assuming the same heads and cam the longer stroke/bigger cube motor would both lower the peak torque RPM and also (as a result) lower ther peak HP rpm as well. Normally as stroke goes up the gap in RPM between peak torque and peak HP RPMs narrows proportionally so you need a bit more intake duration to offset that.
