Hp is irrelevant. It torque and where the torque is in the powerband and the characteristics of the powerband.
400hp is great but if you don't start making any power til 4000rpm and it's over at 6500 then that kinda sucks.
A fun engine is a big bore,long stroke,these features will build great torque right off the line. Now if you could incorporate a 6000ish rpm red line that would make for a fun street motor.
It's like comparing a crotch rocket motor to a big cube v-twin. The rocket needs rpms to make power whereas the v-twin has gobs of torque right from idle.
I pick torque
