I might order a set of 456's too, I don't want to go too low?

4.10s should, i dont see why they wouldnt with regular street tires.
but since you have big heavy 20's, it takes alot more torque to move them. give the 4.10's a shot and see how that goes. 4.56's would do it for sure though.

4.10 will smoke the tires all day long

5.10! that way you can roast the tires taking off from 2nd gear

its an auto? so second gear is out but thanks for the input , nice turbo set up!!!

im pretty sure he said 5.10 as a joke lol
if you tried driving on the interstate with those gears, you would be pulling quite a few rpms lol

well now at about 60mph its about 1200 rpms, it never sees the interstate. I think 488 is all that would fit in the 8.8? on wet tar right now it will spin effortlessly just like its on ice,but on dry tar not so much as a chirp so I am going to install the 4.10s this comming weekend and while I'm at it I am going to rebuild the tracloc, right now if you break stand the car it peg legs,so i think at 150000 that it needs some tlc? I have posi add for a ford but what oil should I use in it synthetic or reg? I have a true track in my f250 and that is awesome because you don't need any additives,

you can fit 5.88's in there, but thats not going to help you with a stock ish motor lol
regular is fine, synthetic wont hurt though. make sure to use a 4oz bottle of friction modifier, the synthetics some times come with it already mixed in.

I'll prob use reg oil then I already have ford friction modifier, whats this I read about useing an f-150 s-spring ? and from what year, I still have to hit the dealer for a new one?

Let us know how the 4.10s work out.
