Questions about gear ratio
 

I have a bracket car with a mild 408w shift at 6000.
Car has 4.33 gear and 28" slicks only crossing the 1/8th @5900 was thinking about putting more gear in it.
Looking at 4.56 or maybe 4.71. How much ET do you think this will pick up and which gear should I go to.
Also someone told me with more gear that the car would be more consistent (less effected by weather changes) is this true??

There are some good calculators available online to help when considering things like gear changes. One of them is Wallace Racing Calculators.com

If you have a effective converter that is sized correctly.......
I think the difference between the 1/8mile times with those
gear spreads would be well under a tenth.

The 1/8 mile times on my small block stockers going from
4.56 to 5.13 at sea level were well less than a tenth.

I am pushing 70 and sometimes start in 2nd gear now and then.....
the difference in 1/8 mile is under 2 tenths.

It is sure nerve wracking go thru the lights at 7700 instead
of 6900 in 1/4 miles.
