Need a little help with rear gear selection!

[Fitter480]

Hi guys need some help. I found a tremec T56 out of a 2005 SSR, Took it out to D&D performance and had them go thought it for me. This is what they told me. The trans has a one piece cluster, carbon frictions, triple double syncros and a 32 spline output shaft. The gearing is as follows. 1st= 3.01, 2nd= 2.07, 3rd= 1.43, 4th=1.0, 5th= .84, 6th= .57.

Here's the question: Behind a LS7 in a '67 Camaro what rear gear? I was leaning toward a 4:10 in a 9" ford but now I'm not so sure.
