And a chip is completely worthless and is a bigger waste of money than a "cai" is.

The biggest single band for the buck in performance mods is a gear change. If your car is a five speed, I'd suggest a 3.73. IMO, a 4.10 is a bit too low for a street driven car. If it's an automatic, go with a 4.10. Depending on how many miles are on your car and how hard it's been flogged, you might find your factory limited slip differential is no longer limited slip. If that's the case, go with an Auburn or one of the aftermarket differentials rather than rebuilding the Ford unit. Surprisingly, you will find little adverse effect on gas mileage with a gear change. Below, I've posted a link to a good website that talks about gearing for Fox Mustangs.

Good luck with your mods. BTW, I agree with the comment about chips. IMO, worthless.

i don't understand why everyone insists 4.10s arent good for the street? i love 4.10s in daily driving situations.

because people that have to travel from place to place via the highway, dont like tacking 3000 rpm's at75-80 mph

I have 4.10's in my 86 5.0. I don't have a problem driving it daily on the highway. I had 3.55's before and it really wasn't that big of a difference to me. But I guess thats because I would rather race someone from a stop rather than rolling.

Gears!!! Best bang for the buck...

Next, I would go exhaust andsuspension...

Gears for sure! CAI is a waste money. Drop the silencer and put a k&n cone on it. I'm not familiar with Cali emissions, we dont have to worry about that stuff, but if you can go with long tubes. A little more aggravating install but worth it IMO. Nix the chip, not needed. As far as the exhaust, go with what you like, we have an exhaust sticky. SFC if you dont have them and control arms also. I would get the car set up for the power you plan on having down the road and not even worry about an intake yet. Re-enforce your torque box's also, if nothing else at least weld them good as will as the SFC.
