Default Help me pick a gear ratio please!!

Ok guys I have a 99 Camaro SS M6, I have full bolt on's, LS6 intake, QA1's all around, Adj. T/A, LCA, PHB, TSP Magic Stick Camshaft, TNT Twister Force 2 kit jetted for a 150 shot, My rev limiter is set at 7,000rpm. Right now I had 4.10s in my 10bolt and sprayed her 1 time hooked and broke so now I am getting a Strange 12 bolt with 33 spline axles and a spool I just need to figure out my Gear Ratio that would be almost perfect. I have 28" tall tires in the rear at this time so I was thinking of going to a 4.30 gear but I don't know if I would tag the rev limiter before I went through the traps? If it matters I am at a 3200 raceweightand will only be going lighter in the future!!

I think you would be fine with 4.30's, your max mph would be 136 at the end of 4th.

Go with the 4.30's I have run mine a little on the street with a spool and 4.30's and was very surprised at how it didn't feel too steep. I could throw it in 6th and still cruise.

At 130 mph traps you will be at 6700 rpm's, what rpm do you turn your engine?

I have 430 in my 12 bolt and like it a lot.I have had 410 and 456 also but the 430 has a 10 tooth pinion and is a little stronger.My rpm is 1800 at 70 with a 28'' tire.
