It has come time to decide what gear ratio to put in my 9" rear. I will be running the mickey Thompsons sportsman's 31x16x15. Transmission is 4l60e. Power plant will be ls1,2 or 6. Somewhere around 450rwhp. I want to have the best daily driver/performance setup. I'm coming up with 4.11 gear ratio, 2400rpm at 75mph. I'm thinking I won't have much of a first gear. Then again what do you do in first gear other than burnouts and taking off from a stop? Lol
How light is the car? Heavier cars I would lean towards the 4.11, smaller and lighter you'd still get the punch with a 3.73. Maybe a 3.91 is a good compromise.
