Wade,
Isn't "traction" what you wind up in after being hospitalized from having WAY too much gear in your Cobra?
Seriously, I only have a regular breathing 302, and I'm putting 3.73s in that now to pick up the speed. (Speaking of, anyone out there have a good used posi 8.8 rear?) With my T5, I'd think even I'll be able to spin 1st and 2nd gears.
The mechanic who works on my car has a 514ci with over 600 hp. I think he said he has 3.50's in it, with the toploader 4 speed. He said he can smoke the car in a heartbeat, almost too easy. Other cars he has built like that, with a 5 speed, he recommends low 3's or real high 2's.
