If this was a 3000rpm torque peak motor with a lower power range, I would tend to agree with you.
You're calling Hobaugh's car heavy? Compared to 2700 lbs every car is heavy I guess! His is only 2900 before he adds ballast.

Meant heavier car not heavy.
I don't know s
t about LS motors, and don't care too, just making some assumptions based on their OEM sataus and design parameters for drivability. But from a quick google on the LS tech forum somebody posted this.
"The T1 racing corvettes with stock LS6 motors, and stock air intake and stock headers and cats, then straight pipes are dyno tuned to 385-387 wrhp, 375-380 wrtq with peak HP at 6300 and red line of 6700. and a flat tq curve from 1500 right up to 4800"
I'll give you I was almost 1k off on peak hp rpm but 3000 rpm is about dead center of the torque curve flat spot so maybe my assumption is good or the guy on the LS forum shouldn't be posting.
If this is true the LS makes near peak torque right off idle so he could pull tall gearing but then what is 5th for
and the gap between 1st and second is like the grand canyon so I wouldn't want to be rowing between those gears on an autocross.
