Hi vatdevil. It's a Holden spec (Australian) 6.0L L98 which is very similar to the LS2. Intended usage is 95% street duties with 2-3 circuit track outings per year. Maybe in a heavier car the shorter final drive would work, but it would be ridiculous in the little Cobra. I'd go a taller final ratio if they were easy to come by or an easy swap - mine uses the helical LSD from the Nissan R34 Skyline / 200SX.
