well, I'm basically at the point where I believe 4.10's are the right choice.
I'll be putting these in my 98 cobra. It's basically exauhst and a couple small bolt ons....nitrous, and going to be blown within 6 months. Unfortunatley..I can not really afford to go crazy N/A (even though that's what I'd rather do)...
Keep the nitrous and blower in mind when dropping suggestions.
I've heard anything from 3.73 (no thanks) to 4.56's... ![[Eek!]](eek.gif)

I would go with 4.10s if this is a daily driver mainly. The Abbott speedo corrector is what I use.

if you will STAY N/A go with 4.56s. i currently have them on my cobra. it's not as bad as you think with these 4V motors. i still get 20-21mpg. i had 4.10s, but after a year or so it felt like it wasn't enough gear. if you want to compromise, 4.30s should be good.
with 4.10s my best was a 13.4 @104.5xx with a 1.999 60ft. i haven't had the chance to test out the 4.56s yet.

I say go with the 4.10's if a blower is around the corner.
I went with 4.30's because I plan on keeping it N/A for a while.
Good Luck

What are your plans for the car? Meaning do you plan on racing it at the track a lot, or just mainly pimping it on the street? On the street you will have absolutely no traction with 4.10s + and a blower unless you're on E.T. streets... Just something to think about if you're not going to take it to the track a lot...
I run 4.30s in my N/A Cobra and have basically all the bolt-ons except headers... On the street, its fine as I usually just cruise in 5th... On the highway, the gears keep me from speeding as I like having the tach around/under 3000rpm...(80mph) Plus my car is pretty low in the front so not speeding keeps the car from getting jumpy on the bumps in the road... If I was putting a blower on my car now, I would definetly step down from 4.30s since I wouldn't be going to the track all the time... I would probably put in 3.73s or 3.90s...
later,
-Mike

Ask those that say "4.30's are too much" if they've actually driven a 4.30 geared DOHC 4.6 before.
So far two people on this thread have driven a 4.30 geared DOHC car and said its fine.
