Keep in mind the 15s have taller (27.0") tires across the board. This year, 3.73s have overall gearing that is close to what a 3.55 has been historically, with the older 25.5" tires. So the 3.73 cars really can go out the back end in 4th.Some with 3.73's are saying they can stay in 4th. When I had 3.73's in my 12 gt, I definitely had to shift into 5th. Anything over 112mph, you're going into 5th on stock tune and tire height. Taller drag radials/slicks and 3.73's would be more optimal all else stock.
