i didnt notice hardly any difference in gas mileage at all from stock.....4:10's will be a bit steep if you gonna go FI, if its a DD anyway

Don't fear the gear. 4.10's all the way.

No Prob. Just remember that those numbers will not be exact with an automatic nor a standard. You have to keep in mind the slippage of the torque converter with an automatic and the infinite variables applied to both autos and standards. They're pretty close though.

With all due respect Code3gt, you could probabley get away with a lower gear than 4.11's with the rubber you're running in the rear. I'm sure you've looked into it and I'm just saying........................

I have thought about going to 4.30's, just haven't made up my mind.

Code, if i had a GT, and i was staying N/A - i'd have 4.30's - so I am right there with you.

ok
9" rear = 4.11s
8.8" rear = 4.10

3.73s are USELESS on t3650s unless maybe your running a turbo or KB as ive never driven them, even with a Centri, i would still go with 4.10s

oh and in a t3650, i wouldnt even think twice about 4.30s, their 5th gear is a dog there would be no problem
