Not Ranked
I just purchased a set of 4.10's to replace the current 3.55's. I installed the 3.55's when my motor was stock. Over the years I have made several engine modifications and the happy zone for the motor is now a higher rpm, thus the 4.10's. The cam smooths out and the supercharger starts moving significant amounts of air around 3200 rpm. The top speed in 4th should be about 130 at red line, while freeway cruising at 70 in 5th will be about 2400 rpm. I will let you know how I like the 4.10's next week.
