i dont need help with towing, what i tow is 4klbs max, but i want to make my car faster, without limiting my ability to use my vehicle, for my everyday driving. Also 410's seem to be a sure fire way to destroy my mileage lol

 

People over rate 4.10 mileage decreases. From what i've seen most people don't even notice the difference. Plus with that cam if you get it tuned right you will probably get BETTER mileage if not break even.

 

when i had the little 4.8 in mine, i had a tune, no cats, magnaflow muffler, servos, 3.73's and i got 20 - 22mpg i switched to 4.10's and still got 20 - 21mpg so no decrease here

 

right now with 228 cam, lt's, 3800 verter, 4.11's, stuff thats suppose to hurt mileage im still getting 17 - 18 mpg
