Jpar, while I have not had that much power on the street, what have have done in the past with my heavier E body 4spd and BF Goodrich tires was a low rpm dump or a slight higher rpm launch with a slower engagement of the clutch. Once it grabs, the pedal goes down as quick as the tires can handle it.
It takes a lot of practice and understanding of the road and the day's conditions to learn what the car will handle for that moment.
When in doubt, walk it out, stomp the go pedal as much as permissible by the car.
The E body chassis set ups was never extensive. Basic parts. S/S springs, soft air shocks, dead front shocks, snubber about 1/2 to 3/4 from the floor. 275/60/15 rear tires.
