4.10 gears...not what I expected. - ZR-1 Net Registry Forums

I'm gonna' go the OTHER way here, after I get the pipes hung - 3.45 -> 3.07, since I've lost some top end with the 4L60e. Tach is just a little high @ 70, and it will add up to less wear on longer trips, and less fuel to boot.

I think that 3.07 is my only option here.

I found it interesting to learn that the original track car had a 3.07 installed...
