Optimal 1st gear ratio?

[Jim_PA]

I'm looking at either a GTO or F-body T56. It seems to me the GTO ratios would be pretty good with 3.73's or 4.11's.

I'm almost thinking I'd want 4:56's with the F-body T56

4000lbs, LQ4 -> Hoping for 450 FWHP from the LQ4 with 243 heads and Lunati 227/231 @.050 with .650 lift. on 112 LSA -- Advertised 2200-6800 RPM in an LS1

Current gear ratio is 3.73 with 26" tires

GTO T56:
2.97:1 2.07:1 1.43:1 1.00:1 0.84:1 0.57:1


F-body T56:
2.66:1 1.78:1 1.30:1 1.00:1 0.74:1 0.50:1

What would be an optimal gear ratio to use with either trans for launching, and which set of gears do you think is better?

2.66 is my current 1st gear ratio with the Super T-10, and I know it's not optimal for launching, but I'm not sure how high I want to go.

Thanks
