Most of us get hungry for hp and pile it on one way or another eventually. These Foxbody cars are on the lighter side of weight so they don't really need steep gears to get them moving. I think the best overall choice for a 5spd manual car is 3.55. For an automatic, go with 4.10.
My 5spd car has 3.73 because that's what was available to me at a good price installed. A local guy sold them to me and installed for $300 total, parts and labor. The gears came out of a Mercury Mountaineer. I supplied him a shim kit and bearings at my additional cost. All told the bill was a little over $400 for all parts and labor.
With the engine mods and V3 I've done, if I had my way, id rather have 3.55 than 3.73
Same guy that installed my gears has a 93 notch 5spd with big turbo on it. He currently has 3.73 but runs them out before the end of the 1/4 mile. He's looking to take the 3.73 out and put in 3.27. His car will get into the 10's.
I say if you're going to be building up engine to anything near or above 400 crank hp, 3.55 is the steepest I would recommend for a manual transmission car.
