i have a list of mods on my stang. with the suspention, i have strut tower brace, full lengh subframe connectors with seat supports. eibach sportline springs, with kyb gr2 struts and shocks. bbk caster/camber plates. new 94-95 lower ball joints. sn95 spindles calipers, brakes, etc. i also have 94-95 axles with rotors in the rear.99 cobra wheelswith 245/50/17tires. i have bbk shorties, bbk xpipe, 2chamber flowmasters, bassanii tips. 190 fuel pump, motocraft plugs, 8mmfrpp wires, powerdyne supercharger 6psi. aluminum radiator. king cobra clutch, preasure plate, and HD throw out bearing with a pro5.0 shifter. the motor was rebuilt about 7K miles ago with .030 pistons. everything else is stock. heads where completly gone threw and so was the motor. still runs great to this day. the car has stock gears (308's) but i wanted to go with a gear that i have already had for quite some time setting up. it's a frpp 355 for my car. i'm feeling the car have plenty of tourqe in every gear and along with HP. i was wondering if the gears will make a big diff? with a new cobra intake and 65mm tb and bigger mas air meter and going to a smaller pulley on the charger (9 psi) will this be the great all around driving car that wont slack up side anything in my bracket? thanks for any advise!

I would go with 3.73 on your car with that setup. Welcome.
