410 Gears

[Loosehorse]

Can any one tell me what RPM your new 05 or newer S197 is turning at Speeds of 70 mph with 410 rear end?
I have 07 with Comp Thumper Cams.
Thanks

I'm just guessing at the top of my head, but I believe it is around 2800 or so. I'll post back later and let you know.

At 2500 RPM's it's just under 75 MPH. But I have an auto and really big tires.

2400 rpms @70 mph with factory 18s.

i'm at 2200 with 4.10's and 27.5" tall tires

It's going to be different depending on Auto or Manual too.

What I can't seem to figure out is what the real gear ratios are for the auto. Like for O/D for example I see either 0.71 or 0.75. What's real? LOL!
