Hi all,

Project car is starting to eat my lunch money. So this is my dilemma. After determining that my sons 67 had a C-Clip eliminator modification performed on it I went out and found an original equipment rear axle from a Nova.

The gears that came in the 67 are 2.56, don't honestly know if they were stock or not. At this point the car is far from original equipment so it's not a factor.

The gears that came from the Nova are 4.11's.

Currently it has a M22 Transmission and a Small Block 350 that came out of a 72 C-10 pickup truck according to the engine stamp. Don't know how long the engine will last and at this point I don't know what kind of performance I'm getting out of it. All I know is it was running when we started the project.

Question: What would you put in it for gears assuming I keep the M22 and 350? This is just a good looking street driver, not looking snap any necks off the line.

Thanks for the help.

 

4.11s aren't going to be too bad as long as it's not driven on the highway. If you want something a little better for cruising, anything between 3.23 and 3.73 will still give good performance while remaining fuel friendly.

 

Agree, something to think about, with a stock size tire, 3.73's, and a 1:1 fourth gear ratio, engine rpm will be around 3000 at 60 mph.

 

again 3.73 and i love the color

 

If you're never gonna hit the highway, keep the 4.11's. If you're rarely gonna hit the highway, keep the 4.11's. If you plan on doing combo city/highway driving, I wouldn't go lower than 3.55's.

 

I'm running 3:73s with a 12 bolt limited slip and a muncie 4 speed and a 396 375h and turning 2600 in 4rth gear at 55 mph. I love the pull it has but hate the milage!

 

If you still want decent fuel mileage and performance a 3:55 is great. Not to low and not to high a ratio. That's what I have in one of my '69's, 350/M21/3:55. Although I'd prefer the Muncie M20 with that ratio. My other '69 is a 350/M20/4:10 and it loves the gas stations but it's quick off the line. I get about 20-22 m.p.g. with the 3;55 set-up. Both are posi of course. If you plan on driving on the highway a lot, the standard 3:08 ratio will give you the mileage you would want for that.

 

In ordered 3:08 last week and they arrived on Friday. I will be putting them in my 12 bolt on Monday.

 

I think you will like the 308's as i have them also--i don't race much and with the price of gas i LIKE them even better--

 

You will like the 3:08's. Great for a daily driver or the highway. You will like the mileage and decent driveability. I used it for years and was pleased with it.
