Anyone with a 383+700R4+3:73 gears?
Anyone with a 383+700R4+3:73 gears?
Hello everyone, like the topic says, I am wondering if anyone has this combo and is happy with its performance. The main thing being the gear ratio, I currently have a 3:27 axle ratio and am considering upgrading to the 3:73's. Car will be daily driver with weekends at the track.

ihad 3.23's last spring, and i installed 3.73's, and WOW... the car is so much quicker, i woundnt mind going to 4.10's but i think 3.73's are perfect for what i do.... street/strip
not a great idea if you are staying with the tuned port intake. I have the same combo but with a 350 instead and the TPI intake and lemme tell you that it runs out of rpm fast. couple that with a high stall converter and my motor is practically worthless with a 1000rpm powerband (3200-4400). I can go thru 3 gears in 5 seconds. good thing I have a HSR and Dart Iron Eagle heads coming in a day or two. Remember -no higher than 3:42s for a LTR setup.

mine topped out so fast i hit second almost after 60ft....... i mean it was topping out severly and i think that it help kill the first motor.. well that and n20 lol......
3.73's are to me perfect for the street, and even better if ya have an od tranny........

I drive mine everyday, no big deal. 4.10's would be even better. If I ever break these 3.73's, I'll put some in.
