Question about going to a low 1st gear in a C4
 

I have a bracket car that runs 6.70's in the 1/8th with 1.43/1.44 60ft
The car has ladder bars/coil overs and i run a 28x10.5 bias slick weighs 3100lbs with driver
I am a huge fan of stock/super stock, especially the wheelstands.

When my car leaves it picks the front tires up about 8" and carries them out @20ft. I would like it to pick them up even higher
I was wondering if i put a low 1st gear in my C4 if it would make a big difference in how the car leaves. Also would it effect how the car runs.

its probably more the converter and the rear gear that will make the difference. Also how the engine is tuned. My powerglide has a 1.98 low gear and will get the wheels real high if I want it to. I am sure your C4 has a lower gear than that. The engine that I have in the car now actually likes a real tight shock setting and keep the front end down. Each combo will like something different.

I agree with Mr Pearson. It is more the converter than the low gear set. The stock c-4 has a 2.43 low gear. I run a SS/GT mustang with far less than the stock ratio and my car will drag the bumper without the front end tied down and 50 lbs of ballast on the front.

so are you saying i need more converter?

Also, if you put in a lower first gear, it will definately affect your converter. You will find you won't be able to leave at the same RPM. It will not stall as high after you install a low gear.

I would start with another converter too. What engine are you running now?

There are too many unknowns to make a blanket statement.
Camshaft?
Heads?
Carb?
HP?

The more obvious question should be "Why do you want to pick the wheels up higher" It will slow you down, maybe make you more inconsistent, possibly cause a dangerous turn of the car???? If you want to improve the 60 ft or et then other things should be considered first.

Why don't you just put a bunch of weight in the trunk?

Just remember its the car accelerating that causes the wheel stand, not gearing.
