I have a 94 LT1 6-speed car with heads cam and sray, I had a stock 10 bolt and broke it. I found a sweet deal on a moser 12 bolt. It had a set of 4:56 gears in it. My problem is threw a 1/4 mile im running out of gear and having to shift into 5th gear. Any suggestions on a good ratio would be great.

What is your trap speed and maximum RPM?

4.10s or 3.73

Quick fix, By a taller tire. Problem solved.

I run 4.30's in my 9" and run 26.5" tall tires at the track I trap at 6500 RPM's in 4th.

4.10's would be perfect. I'm also about to ditch my 4.56's (same deal as you, they came with the rear) in favor of 4.30's.

pick a tire first, then the gear based on your mph

^^^^Agreed, don't go about it backwards. Figure out tire combo and then buy a gear.

I am currently running a 26" DR, but will probably buy new 26.5" DR. Im turning around 6400rpm and falling probably 450- 500 ft. of the line in fourth. What do you guys think? Jaws if you carry anything for a moser 12 bolt i would be interested.

depends how high you are revving, stock cam or bigger cam? there is a calculator.. and if you know what speed you are trapping at use the calculator and see how tall a tire ure gonna run, etc.. and what ure 5th gear is... probably .74, but IDK about LT1 T56s...
