Is anybody running 4.30's on a n/a manual car? I have 4.10's now and am thinking of going to 4.30's. How are they on the hwy? I am also running 35 series tires out back so that makes the ratio even lower. I dont wont to get it where its not drivable.

I had 5.14 gears in an '68 Camaro with a small block 327 back in the day. 2 speed powerglide w/ nitrous. It was a 8 sec. street car back in highschool. Obviously a little different gear then your post suggest, but nothing I'd even consider putting on the freeway. I think 4.30's would put you close to being in that same category. Unless your planning on putting the thing on a trailer to get it to the track, it's too much.

If he had an Auto, I think he'd be ok though, but with a Manual Trans it would be a bitch for a street car, and he'd be constantly shifting, as i'm sure you did with your Camaro.

Not really since he had a powerglide which is a 2 speed auto.

It shouldn't be too bad, unless you get on it alot, which you will deff be tempted to do with those gears. Under normal driving though, you might lose 2-3mpg with 4.10's and 1-2mpg with 3.73's. But some people say they didn't lose any, so it varies.

4.30's would be good... with 20"s haha. i seriously dont see why it would be that bad.. you would be in the powerband ALL the time.... its not THAT big of a step from 4.10's... i dont go barreling down the interstates fast as i can so 4.30's really would help me... combine 4.30's with a really short throw and a really tacky clutch, race car like shifts from a mustang... would be fun i think... then again i am ****ing lunatic

my friend has 4.56 gears and those are crazy on the street and at the strip. He gets the jump on me put I pass him towards the end. His gears die out

That step up is not worth the money or hassle...4:10s are plenty short for gears

ya but i am running an auto. i hear that 4:10's in a manual are really different that a auto. so i figure 4:30's will give me that extra edge!
