i was checking into gears myself, since my car is not a daily driver would i benefit more from a 410, or is it overkill and should i stick with my gut for the 373? i think my car is 308 stock. also adding underdrive pulleys( had them for a while but never installed yet) will i pull out of the garage smiling large?? i hear they are the best bang for the buck but just wondering if the pulleys combined with the new ratio will yield a much different feel from the car power/acc wise-

I must be the only guy that likes the stock 273's. With my tremec I'm pullin 2,000 rpm at 70. I guess if I wasn't driving mine daily I could go higher but I like the gas mileage myself. Let us now what rpm's you're pullin and what it does to your mpg's.

finally the gears are in!!!! it feels so nice! a little dronie on the highway but worth on acceleration. still have to do speedometer gear, its off 15 to 20 mph. I ran it at Etown three weeks ago, it ran a best of 15.40 at 91mph bonestock on street tires with the 2:73 gears. can't wait to try it with the new gears
. did new axles,bearings, seals the works!also new quadra shocks and brakes!:rock::rock::headbang::awesomework:gonna do the offroad cat delete hpipe this week. i'll keep posting.

My old 88 LX coupe with 3.73 in it and AOD ran 14.4@99, pulleys, shorty headers, h-pipe, and catback. Then T-5 swap and 13.74@103. If it would have had a valvebody or shoft kit in it the car would have ran much better than 14.4 with the AOD.

I would recommend when you have it all apart, check the differential....and replace if needed with trac-lok.......when I had my 88 GT is switched to 3.55s and changed to trac-lok and it made a huge difference...

I got lucky when i did my gears. I started at 3.08's. I had the car down to a 14.4 in the quarter. I picked up a whole rear axle with Ford Racing 3.73's installed. I had someone help me repack the trac lock and put it in. I can rip the car right sideways like nothing with the 3.73's. Mine is more of a driver than a racer, so if i could have i would have put 3.55's in it. But i got a deal on the 3.73's and axle that i just couldnt refuse.

My car is more of a driver also, how bad did your MPG get with the 3:73's?
what are your rpm's on the highway doing 60-70mph?

Mileage all around has suffered about 2 mpgs. I used to be able to hit 25 on the highway. But now its more like 23 max. My stoxk tach is a little messed up. But 65 im gonna guess im about 2100 rpm.

I had 3.08's in my 83 and my car ran 12.6 @ 110, I put a set of 3.73's in, and ran 12.3 @ 115 mph. 4.10's put me at 12.0 @ 115. This might be irrelevant because I'm running a c4, but I can tell you this, you won't be disappointed.
