Rear End Gears......Help!

[Performer5Oh]

I am looking one day to get the crappy 2:73 gears outta my 5.0. I want to go to a 3:55 or a 3:73. I have a AOD, and it will have a 2000-3000 street/strip stall converter. What is the best gear for my car? How much difference will I notice it being a auto?

Thanks
Randy

With an auto, I would go with the 3.73 gears. I had some 3.73s in my 90 LX 5 speed 5.0. It really woke it up. I could smoke the tires in 1st and 2nd, and chirp them hard in 3rd. I could take off in 2nd easily and I once let a girl drive it who mistakenly took off in 3rd:??: car did not mind it too much feathering the clutch like she did:gt:. I would say to go with the 3.73 gears. If you really want to get that auto moving, put in some 4.11s. They would probably be too low for everyday use.:thumbsup:

yeah, well one day I was planning on putting a C-4 in it. I think i'm gonna go with the 3:73's..... What do you think my 1/4 times will be with the 3:73's... And I am gonna also put some wider tires on the back. Now I have 225/60/16's. I'm gonna go for some 275/60/16's. Thanks

It would be hard to say. If you have never driven your car at the track, it may be slower than you posted above. If you are a fair driver, it might give you 2/10ths or so. Don't quote me on that, I can't remember what the average is.

I think I am a fairly good driver. Since its auto, theres not much shifting to do. I do the 1-D-1 shuffle though. I think with the gears, better tires, and a stall I could get mid-low 14's.

With the heavier convertible and the auto, I would definitely start with 3.73's. Is the car your daily driver? If you are only interested in quick acceleration, then maybe a step up to 4.10's would be in order with the AOD. If you switch to a C4, 3.73's would probably still be best. Just my $.02

Yes its gonna be a daily driver, i'm only 16. I am going to buy some FRPP 3:73's soon. I've also heard of the motive 3:90's, I don't know how much they are though. After the gears, stall and aluminum driveshaft with traction i'm hoping high 13's. I doubt it though it will have to go on a diet and a couple of more bolt ons to get in 13's.
