4:10's or 3:73's in an a4

    I graduated from high school right into the 'original' muscle car era. typical FACTORY options were up to 4.56,the 69 camaro even had 4.88 in the option code. gears back then were used to make cars into 'light to light' streetfighters. the dragstrip was OK but the street is where you earned respect/fear.
    I love the overdrive trannys,gives me the ability to have the best of both worlds,a wicked gear and decent mpg. I used to get 6mpg in my 65 gransport when I would rejet the carb for strip duty.

    I can understand that. I just can't bring myself to shove an overdrive in any of the classic cars. Just seems to dampen the experience, well that and the fact that they are getting to be worth too much money to decimate like that.

    That's just it, alot of people drive around like there asses are on fire and think they need to be somewhere. I'm of the mindset that 55-60 is fast enough for any of my "geared" cars, and I allow enough time to get there, never in a hurry. That's just the adjustment I've been used to doing for 30+ years. Hell that's what we all did back in the day. Guess that's why I never got that thrilled about overdrive transmissions and can't grasp the idea of even contemplating a gear change with an overdrive in front.

    Guess thats where these kids have issues, just can't make that adjustment.
    Exactly. If you slow down a bit you can drive a "geared" car anywhere and be fine. I actually prefer the gears since they kind of force me to slow down. Keeps my insurance rates nice and low.

    I'll be honest though, he is approaching 60, so about 5 years ago he wanted to tame the car back down a bit so he could "drive it" more So I pulled the 5.13's and stuck 4.56's in there. Now the car has gotten too valuable to enjoy though.
    I was running with him in my DZ with 4.88's for years. When that car goes back together it will get the 4.88's again

    We think alike. I keep a certain rpm, and the gears keep the speeds down. I don't have to worry about tickets that way.

    If you go to the track alot and don't mind doing 70 instead of 80, go with the 4.10's. With the converter locked in 4th, at 70 you'll be around 2700 rpm and still get about 20~ mpg.

    agree^^^ ! 4.10s'. better acceleration than 3.73s' provided you can get traction.

    Yeah im not too worried about MPG's. however i do love cruising at 80 so im thinking that 3:73's will be better for my application

    To be honest, I haven't been able to do any WOT pulls with my car yet.....with my new setup, my trans is slipping really bad WOT in 3rd (hitting my 6700 rev limiter at 65 mph in third gear). Use this link to see what you are comfortable with: http://www.f-body.org/gears/

    A double duty car is always hard to pick a gear for. It really depends on what you are willing to deal with.
    Like I mentioned earlier, most people here try to daily drive their cars while at the same time making them fast straight line performers, that's a difficult feat to pull off without giving up one or the other, and it seems most here like to use the 3.73 gear as a compromise. With the overdrive that should be a piece of cake to live with compared to what I'm used to.
    For me even the 4.10's aren't bad. But I come from the other side of the fence. I prefer to gear a car according to what the engine needs to run the quickest 1/4 mile time possible and then what ever that winds up being, I deal with it on the street. I simply adjust my driving speed, whether it's 55 or 70 mph it doesn't really matter to me.

    But if you think like most do around here, I'm betting the 3.73's will give you what you want.

    i see and you would be correct also i talked to one of the guys at my shop and he said that i would be worth it to just save up and put a dana 44 with a nice set of gears since their strong and i wont have to worry about having to tear it down and fix it in the future when it eventually breaks

    Hey old timer , it's a fast paced world out there, no time to slow down for us. emails, a bunch of text messages, High speed internet, TV, Fast food, no sleep...

    The gear ratios you are quoting are generally used for 1/8 mile tracks, no one in their right minds would run these gears on the street.

    I guess I'm out of my mind,lol. Since 4.56s' with my A4 were the highest numerical ratio available for our little 10 bolt,I was limited to them. If 4.88 or 5.13 was available,I'd use those.

    In the standing mile I'll whip all these cars... that's the beauty of picking the right gear. while your car will max out at 135mph... I'll be cruising at 180 by you. If I were to decide to mess with you while you were cruising down the interstate at a normal 70-80 mph, my car with the higher gear will pull harder.

    If you want a full on out drag car that's good from a dig on a well prepped track in an 1/8th go with the 4.00+ gears.

    Better be prepared to get slicks just for traction, then a drive shaft safety loop so when you break the shaft it doesn't tear the whole bottom side of your car up, and in the end you'll need to get a 9 in. or 12 bolt because more than likely your 10 bolt will not be far behind the shaft in utter destruction.

    too much at stake for a poor guy like me. if you're like my friend who has a NBM WS6 w/ 4.10's you'll go through these steps like he did. his car is a manual though and he always launches between 2500-3000rpm's. his car w/the double overdrive turns about 2000 rpms cruising at 70, so with a stick your options would be a little bigger.
