How about in a 3300 lb 327 GT car, 2.08 low, very good PG versus a 2.52 low, very good Rossler 350? The PG is in the car and I have access to the Rossler.
Any data or thoughts?

Exactly! Get that pig of a car moving as quickly as possible! If I hadn't just invested a ton of money in a 2.03 powerglide, I would have taken advantage of a th400. Big wheelies, and should be quicker.
