Does anyone know what rpm the M6 ls1 runs at 65mph with 4.11 gears in a stock 10 bolt?

Mean Machine

in sixth gear, i average 1700-1900 rpm at 65 mph.

Yeah, I agree with MEAN MACHINE, i average near 1800 @ 65mph. The 4.11s are hardly noticable while cruising on the highway, but its nice when I don't have to shift to 5th or even 4th to pass someone; all I do is giveit a bit of gas. Granted with my H/C set-up I have a completely different power band over a stock Ls1, so that helps to. But just the other day I was driving my Ws6 on the highway and some ******* was about to cut me off (I was in 6th gear @ about 55) I punch it to close the gap so he wouldn't squeeze in there BUT the damn car didn't go anywhere(I am used to having the 4.11s and another 120RWHP ) . When I get my 12 bolt for the Ws6 I am going with 4.30s.

If you cruise at 65mph, your rpms will be under 2k. By cruising at that speed on the freeway, you can still keep your mileage over 20mpg.

I think hands down, 4.10s are the best overall gear for street strip with an M6. As said above, highway driving is a pleasure because I can pass people with easy in 6th gear.

what he said. 4.10s work great for the M6 on the street.
