D100 + 440 + 727 + 3.91 = tire spinning. Oops!

I agree faster but, the 3.23 will require more torque and throttle to do so. I’m suggesting that the 3.23 won’t be as easy to get it spinning. I went from 3.55 to 4.56 in my other truck and slightest throttle would make 4.56 spin. With the 3.55 I really had to get into it to spin tires. If what you’re thinking with the 440 it may not matter.....it’s going to spin, you’re correct.

Yes. If it breaks loose now, the 3.23 will make no difference there. The 3.23 is only going to make the problem worse. With the the 3.91 the tires will stop spinning much sooner. WIth the 3.23 they'll spin forever. lol
