I picked my cam when I was doing HPDEs in the car... I wanted a higher end powerband because the car is rarely below 3000 rpms at VIR etc.
My car is no slouch down low like some huge cammed cars... the LSA is actually a 114+4 so it has advanced ground in and makes good mid-range. Yes I could have a stump puller cam for the street, but that'd just result in more tire spin. Even w/ the 3500+ cam powerband the car will still roll the tires over in 1st and 2nd when leaving from a roll.
If you compare my bolt-ons dyno to my cam dyno you'll see that below 300 rpms I'm down about 5-7 ft/lbs, then from 3000-3500 they're equal, then after 3500 everything goes up.
