My friend just got a 97 Cobra and is thinking about swapping in the 3.73 rearend out of his 97 GT into it and then putting his NX kit on. We all know if you search you will find alot of dragstrip only guys like 4.30's and 4.56's but for a nitrous car that goes to the track sometimes and also likes to run big cammed LS1's and 03 Cobras on the highway, 4.30's and the nitrous seems like too much.

Alot of guys like to run from 40 around here because it's just hard to find a place to stop race. Call it ricer or whatever but sometimes it's more fun to beat people at their own game anyway. Has anybody ever had 3.73's and 4.10's and PREFERED the 3.73's on the highway from a roll? Wonder how much is given up at the track with them? We only have 1/8 mile around here.

I have a video of two bolton 96 Cobras racing, one had 3.73's, one had 4.10's, the 3.73 car slowly crept out to 3/4 of a car ahead from a 40 roll, the 4.10 car won by like 1.5 cars from a 15 roll. Interesting. Maybe 3.90's would be a good compromise?

There used to be a local that had a bolton 98 Cobra with 3.73's and a NOS 125 Dry shot, it ran pretty good.

Freeway racing definatley 3.73's. Freeway races can take you to speeds of 130+. You won't run out of gear really fast. Put it this way both my cobras whe nI had them

96---4.10, Vortech, 414RWHP 12.50's 116

97---3.73, stock..say 260RWHP 13.90's 102

From a 70 roll or an 80 roll...my 97 would get my 96.

Back in 02 I had a 95 GT with a Prochager 11lbs, built upper end. The car had a 3.08 gear in it.....very fast...beatable off a light, but UNTOUCHABLE on the freeway...I would drop it in 2nd gear at 60MPH...11lbs of boost at an instant, and I would wave BUUHHBYE to anybody.

I would go 3.73 for freeway, 4.10 or higher or 1/8 th mile.

IMO, if you are racing on the street and have to go over 120mph you already lost...besides, racing to those speeds on the streets is just plain idiotic and stupid...

With that said, I say 4.10's...they'll still take you to 127mph before you have to shift to 5th...

3.73's are a weak gear N/A on these cars, and you won't always have the bottle on or have enough in there to run it so why not go with the 4.10's...

We dont live in a big city so it's not the same and people dont race down regular streets at those speeds.

You are right on the 4.10's being better n/a and probably not too bad on the bottle. Hmmmm.
