Any idea on how slow I might be from a dead stop with the 3.27? After reading all this great information, I am again leaning towards that. Unless it's still going to be a turtle.

I can probably improve acceleration by freeing up some usable hp with an e-fan and maybe an aluminum drive shaft. Building a hybrid M5OD-R1/HD transmission would definitely help but be pretty expensive.
Basically, in terms of power to weight, your 5th gear is like my 3rd gear (closer to my 3rd than 4th). If I want to accelerate like you can in 5th right now, I downshift to 3rd. If I want to accelerate like your 3rd gear, I downshift to 2nd. I just have 2 more gears on top of your 5th gear for economy, while effectively having not as many choices in the middle.

My car still scoots in 1st and 2nd. I can just leave it in 1st and 2nd much longer.

EDIT: So it would be somewhat akin to your new gearing being something like:
1.25st gear
2.5nd gear
3.75rd gear
5th gear
6.5th gear

My only concern with taller gearing personally would be whether you'd go past the point where you can no longer reasonably use 5th gear, but I don't think you'd be anywhere near that with a 3.27. Maybe with a 3 or less.

My 2 cents.
