The 5.0 will have the same exact advantage rolling it does at the track against the ss.
This is what you continue to deny and assert "nooooo ls are roll monsters, pull better up top" and yet can't point out any reason why you think this. Not the gearing, not the power curve, nothing, you just say it out of emotion for your car.
But I'm the dense one...
It has nothing to do with emotion. Do you think I give a rat's ass if a car is faster than mine, especially stock vs stock? I couldn't care less. All it takes is money and who's got the deepest pockets. I say it because that has been my experience. I stated real world scenarios that actually happened, not some dumbass dyno sheet and theories about it.
