Question about gear swap

68Mustang · 12-07-2009, 02:36 PM

I have a bracket car i usually run 1/8th mile finllay ran 1/4 mile a couple of weeks ago car ran
1.42
6.69
101.4
10.59
123.8MPH.
The problem is I have to much gear is it was crossing @7000. With my current head and cam combo the motor makes peak power @5800/5900 and I really only want to turn my motor @6500. I run a 4.56 gear and a 28" slick
So my question is should i swap to a 4.33 or a 4.11. Also I feel the current gear hurt the car in the 1/4 and the swap will help the car but how is the gear swap going to effect my 60 ft & 1/8 mile times.
