yeah because my cougar that is going to have those gears in it is going to be my daily driver. so a speedo is needed around city streets. then my other car when i get it is a 85 turbocoupe to be a beast on the street/track just like my cougar. so is there a speedo gear for my cougar setup?

There is no gear that will even be remotely close for 5.13 cogs...

In the old days they had adapters(a small gear box) that mounted into the transmission and the cable(with gear) went into the adapter... By juggling gears in each you could come up with about any combo imaginable...

That much gear on a C5 is going to get real old in a BIG hurry... Be like driving in second gear...

What would I use?
275/60-15 on 15" rims, c4, 3:50 rear gear.

 I think I got a purple gear in there now. I know it off.

How about 4:10s tops for the street and even that is to much gear!!
3.73's would still be high for a 3speed but would be much closer with a 23tooth.
