I don't know the real numbers, but compaired to my 98 isb 5 speed 3:55's and my 2002 Auto 4:10's, I feel it pulls harder then they did at low end, then it starts pulling real hard, then just runs out of steam, you look down and your up agains the rev limiter. (that's why it ran out of steam). In other words, it rips! take one for a ride.
