I am looking at a 84 camaro with a doug nash five speed and was wondering what everyones input was on them. It has the 3.27 first gear. It has a 4:10 Dana 44 in it and I think that is WAY too much. The car tops out at 114 and runs 4000rpm at 76 mph. I was wondering any suggestions to what gear I should change

 

Those gears are not that bad, some camaros came with those stock.

If you switched to smaller gears maybe low 3's or high 2 I think there would be some difference. I think The most difference would be changing the tranny.

 

Yeah but the tranny is the best part....that thing can hold alot of power...which I plan on putting to it. I think a 3:42 will be the right thing for it. does anyone else agree.

 

Put larger diameter tires on. Much easier than changing gears, and it changes your effective rear gear ratio. Not to mention the traction... oh, the beautiful traction. Might need some bigger wheels too. It'll look better and perform better.

 

that larger tires will make your gears seem lower?

and smaller will make them seem higher?

I think that is the way it is but just checking.
thanks =):hail: :hail: :hail:

 

Thanks alot the wheels are 16's but I don't now the tire diamater I will have to ask him about that. Thanks alot guys, for all your help.

 

Hope you work out your problem.

Do you know what your 0-60 time and/or quarter mile?

Just wondering, It sounds like it must be quick if the top speed is only around 110.

 

Large diameter tires makes the gear seems numerically lower. i.e. a higher top speed. People on this board keep talking about getting higher gears like 3.73 and 4.10, but what you have to realize is that if you gear it too low (higher number) you can actually slow down your car instead of speeding it up.

For instance, if you go to 4.56 gears you'll probably waste all your power on wheel spin and by the time you change gears you've wasted half a second. Not to mention the possible changes to your power band. If your power band is between 4500-5500 RPM and you only spend 30% of the time there, you're not going to be very fast. Take everything into account, including rear gear ratio, tire diameter, transmission ratios, and engine power band before you decide on a change.

 

Trux..the guy I am going to buy it off of sid he never made a pass in the car. He had the engine in 69 camaro and made one pass on the engine and got a 11.2. With the gear and the engine along with the trans he said it should run 11's. I am hoping to make a pass or two and find out if I buy it.

 

good luck with it if you decide to get it. Sounds nice

I also purchased a vehicle with the same tranny. The manufacturer's literature recommends a gear ratio between 2.73:1 and 3:36:1. With a 3.27:1 first gear, you won't need a real low (numerically higher) rear end gear. The 3.42:1 ratio you mentioned would probably work pretty well. It also depends on your performance goals and intended usage. If you ever intend to drag race the car (esp. with larger diameter tires which yield superior traction) I would think the 3:42:1 would be a good setup with an engine designed to run in the RPM ranges of most warmed over street engines. If you build a high-rpm street/strip engine (6000+), a 3:73:1 might be better.

 

I have a G-Force 5 speed transmission, it is geared very similar to the Doug Nash. GregC is correct about the gearing recommendations being 2.73 up to 3.36. You should stay within that range for a street car. I currently run a 2.86 (F*rd 9") and am very happy with that gear.

 

Thanks alot guys i guess I will have to take out the dana44 4:10 and put in a 3:42 or smaller depending. I am looking for a street strip out look and it revs to 6000 so I think that will work well. Thanks alot guys for all your info I really appreciate it.
