I changed it to a 4.10 and now I run 1750 at 65. Much,much better. I can still run 40-45 in 1st turning 7000. My gearing is perfect for me and my motor combo. My LS1 idles at 900.

Hope this helps.

I think the old F-body 6 speed was a .50 6th gear though

Looks like it has pretty much been answered already but I'd shoot for 65 MPH cruise right at 2K RPM. 4.10 should put you very close.

Of course you want to make sure your T56 1st gear is friendly to that 4.10, what is your T56's first gear ratio?

I haven't driven mine yet, but I've talked to a million people (not literally) and they all said 4.10 with a 305/30/20 that is a 27" tall tire and my T56 Magnum. But hey, like I said, I haven't driven mine yet. So what in the hell do I know?
