How much gain with lower gears?
That's a pretty short tire. I'd be willing to bet you won't pick up any ET in the 1/4 going from your 3.23s to a 3.55 or 3.73 with your mild 408. With my old 408 duster, i ran identical ETs with 3.23, 3.91s and 4.88s. I was a kid then and had no clue what I was doing, but they're data points none-the-less.
