As it sits right now I have 3:31's but with the upgraded 20's It has fallen some. Judging by the Tire size calculator Im ruunng somehwere around 3:19's or so. I originally wanted 3:55's so with this difference Im gonna go 3:73's and hopeflly my ratio will end up somewhere in the 3:60's.

Any input on this? Im also buying OEM Ford gears and not Ford Racing as they are made by a different company. I can get gears and bearing brand new from dealer for $152.00.

Depends on your goal for the car. strip? autox? road race? roll race? I have 3.31 but with the shorter tires I will be running with my track wheels it ups my gear ratio right where I want it so I will likely not change mine.

I do for the forseeable future. Car takes awhile to climb the RPM band now. Its noticable.

I had 4.10s in my 5spd GT and they were awesome.

If your long term plans include a turbo(s), keep the 3.31s.
Otherwise, 3.73 is a good street, strip, 1/4 choice.

No F/I. Maybe juice later on but mostly motor.

I'm in the same boat as you with 20's and 3.31's and yea....it take a while to climb. I'll be getting 3.73's here in the next month or two. If I get mine done before you I'll let you know how it is.

Just add boost, that will help it climb faster. Lol

That 3650 also had much different gear ratios.
