I would think a 3.55 - 3.73 range with a quality convertor 2600-2800 would do the trick. You might want to check with ATI and give them your specs and possible rear gears and see what they recommend. Another thing to consider is the transmission...is it bone stock? shift kit? performance governor?...

The original L78/LS6 packages had a HD TH400, 6 lug convertor and a special governor that allowed for high rpm shifts...around 6200 rpm.

If the rpm's don't scare you, then 4.10's will really make it jump.
