Best T56 Magnum/ rear gear combo

[workng247]

Looking to get some input on what you guys would consider the best trans/ rear gear combo for my upcoming 69 Camaro LS swap. I'll be using the LS3 480hp crate engine and a T56 magnum. Looking for best all around street performance. I have original 12 bolt with 3.42 and Truetrac now. Will change gear if necessary. So, which version of the T56 would you recommend and why?

Thanks
