With a m6 car, 4.10s/11s should be the choice without even thinking about it. I had a buddy on here get a 12 bolt with 3.73s. He said he could barely tell a diff. So, after a very short while, he swapped them out for 4.30s. Now he runs a 9in with 4.11s. I have 4.10s in my car, and will never have a NUMERICALLY lower ratio than that.

Kiss your fuel economy good-bye. I had 4:10 and switched to 3:73 instead. I know a couple guys that did the same thing.

I still get 24-25mpg with my heads/cam/4.10 setup. Last time I checked, it was 24.86 to be exact. With no highway runs longer than 5 miles at a time, beating on it quite a bit, and several 100+ pulls, it still gets 20+, most of the time about 21.5

How come you put a corvette intake on your car? From 01 on up to when they got rid of the 5.7 LS1/LS6 which 04 was the last year of them the corvettes and camaros had the exact same intake manifold, which would be the LS6.

Default 3.73s or 4.10s

Hi,
I don't have an LS1 yet, but I would go with a set of 3.73s. I've had stock 3.42s, 3.73s and 4.10s and I feel that the 3.73s gives you the best of all worlds in terms of coming out the hole, midrange, topend, cruising at 70-80mph, and fuel economy. Like I said, I don't have an LS1, but in the case of my LT1, that was the case.
My vote...3.73s.

-Tim
