Gears
3.73 or 4.10 gears for an 1987-1993 5.0 mustang? I want it to have fast acceleration, but dont want to over stress a pretty much stock engine with 4.10 gears. Am i going to feel a diffrence with 3.73 over the stock gearing. What you guys think? :?

I wouldn't go to the 4:10's until you run it at the track to see what rpm you cross the traps at. Then again I'm not too familiar with 5.0 Motors.

What rpm on average should i be at when i cross the finish line. What rpm is too high and what is too low? Sorry for the ignorance. :( ](*,)

Hey Mr. 5.0 (JZ) want to field this one?

Sorry, saw this yesterday, been crazy at work right now.
It all goes back to what you want out of the car. If it's a daily driver or if you intend to supercharge or turbo charge at a later date then 3.55 might be the right chose. A cruse car that sees a lot of track time would probably gain an advantage from the 3.73. To benefit from 4.10 you'll need a higher revving combination, also first gear will be real short with the 4.10. You still have the overdrive, but no more long trips at highway speed. For a mostly stock 5.0 you’ll want to shift at 5250 and cross the finish line at 5500. I went with the 3.73’s myself, however I use a C4 3 speed automatic. My car is set up for mostly track with limited street cruising. Your car probably came with 3.08, could be 2.73. Usually only the automatic cars came with 3.27. Yes you will notice a difference!! |
Thanks a lot that really helps. 8)

Where would you guys buy these gears? What are some good websites or stores that sell diffrent types of gears? :?:

The Ford Motorsport (now Ford Racing) gears use to come with the shims and everything you needed.
Summit or Jegs usually have the best pricing. I like to support local venders when I can but usually they can't touch the mail-order pricing. http://store.summitracing.com/egnsea...962+115+400070 Since you’ll be taking apart the rear to swap gears, how’s the traction-loc? You might want to freshen it up. I have some good links at home on the traction-loc rebuild. New clutches only cost about $50 and you can put extra disks in to help with traction. I did that and used the F150 S springs when I rebuilt mine. |
Hey Shicaca,
Here's a really good 8.8 Rebuild page http://www.angelfire.com/oh5/cpa5oh/cpa5ohtech001.htm this is the alternate Traction Lok clutch disk stacking order http://www.angelfire.com/oh5/cpa5oh/cpa5ohtech018.htm hope this helps |
