Car is fianally on the road...but i have some questions...

[hoss331stang]

Ok, my mods are in the sig.....and let me tell you, this thing is mean.....i don't know what kind of power its putting out, but it feels fast enough for me.....a whole lot different than it used to be.....But i have a problem...My car still has the stock 3.08 gears in it, i just found that out the other day, i thought it had 3.55's but after looking into the case they are stock 3.08's. Also, my clutches on my trac-loc are gone......i only have one wheel peel right now.... (no traction at all)

The question is, if i added some 3.73's, with a rebuilt trac-loc, should i feel a big difference....i mean think about it.......it has 3.08's!! My cam..well.....actually everything in the motor calls for 3.55 gears and up to run well....Should these gears wake it up and put it in its powerband? or will it not make that much of a difference? Any help is appeciated...

I'd go with the 3.73s. That cam really needs a deeper gear and you will notice a big improvement in performance.

Yep 3.73 will make a big damn difference I had 3.73 posi in another GT I hardley ever used 1st gear I could smoke them in 2nd and blow little rice burner's........

"Will it make a big difference?" Your damn right it will, like night and day!

Think about doing a T'Bird 87-88 Turbo Coupe rear end. Auto TC's had 3.73 trac lock & manual had 3.55 trac lock. Disk brakes were a part of the package. The cost of the TC rear end and doing the brake conversion could be less than buying gears and having a shop install them.

And even more than the gears - get something with a tracloc that's working. What good is the power if you can't put it to the ground?

I second that. But I also want to point out that there are some extra cost things you will have to buy to install the TC rear. I am in the process of doing this swap in my car right now. I converted my TC rear to the shorter mustang length so there was some extra work there but the cost is the same. I paid $125 for the 3.73 rear from the boneyard. So far I have spent about $250 for all the stuff I need to make the TC disc brakes work on the Mustang including Master cylinder, E-brake cables, brake lines and fittings, new pads and rotors, etc. I figure all in all the swap will cost me about $400 which is about the same as the cost of gears and installation probably, but I will also have disc brakes when its done. If you wanted to swap your brakes and axles from your old rear, you could get away with just the cost of the TC rear.

Does/doesn't the proportioning valve have to be changed when making the swap if the vehicle's not 4-wheel abs?

You need to gut it and install a plug from the Ford dealer. And I assume you mean 4 wheel disc, not ABS.
