2.73's and a big stall
 

I am a full bolt on car with a pig cam. I have a TCS 4400 about to be installed. I know it will be loose, but i do not mind as i mostly see highway miles. What will I gain going with some 3.42s or 3.73s? The reason i ask is because I always hear people say that gears are not worth it. Does anyone have experience with a 4000+ stall with 2.73s? :) Thanks

I am running a TCS4200 2.7 STR with 3.73s. If not just for performance the bigger gears are worth it from a driveability stand point alone. My car is a pleasure to drive not too much looseness. I have a C5 with heads and cam I run ET Streets so traction shouldn't be a major issue with my car. The 3.73s also make my car a beast from a roll.
IMO go with at least 3.42s.

Re: 2.73's and a big stall
 

Going from 3.23s to 3.73s with a big stall only produces a .1 gain so I wouldn't expect any more than a .2 gain going from 2.73s to 3.73s with that monster.

Hope you have a big cooler for that combo. ;)

I have a 24K cooler. I was asking because my friend has 3.73s with a stock stall, and he has a hard time with traction as it is. I also don't see a nice gain with gears although i might go with 3.42s. How will the 2.73s do from a 50mph or highway roll? Thanks

Re: 2.73's and a big stall
 

with a big stall, the 2.73s will pull hard in 2nd even at 50 mph. The stall will drop the motor high in the power band and provide some torque multiplication to around 70 mph so you'll notice a solid gain.

I've been told that going from 3.23 to 4.10 would gain .1 if you were lucky. I decided to just leave it alone.

I would get 3.73's-I have a big stall and 3.73's and its a great setup-pulls hard and the coverter works well with the 3.73's!! :D

Re: 2.73's and a big stall
 

I agree, I think my money could be better spent on suspension work than gears, and also give me a better gain until i get a 12 bolt with 3.73s :burn:

I pulled out my 3.23 and installed 3.73. I hate it. i wish I would have spent the cash for a good converter instead. I like hitting 160 when I want and now I run out of rpm before I get there. I also lost 4 mpg on the interstate. I drive from Odessa texas to New Orleans every week and the loos in mpg and the gas prices chap my arse. When i get my converter I am going to try it with the 3.73 I already have in it at the track and then switch back to my stock 3.23 and take it to the track. If there is hardly no difference I am going to leave the 3.23 in it. It would have to make a .3 second difference for me to keep the 3.73 in it.

My 2 cents on the subgect.

Re: 2.73's and a big stall
 

Texas, IF you have a good stall converter, the 3.23s will pretty much be as fast as the 3.73s. Very little difference.

Re: 2.73's and a big stall
 

Agreed!! :D

I have a 3,000 stall TC and have 2.73's what gears should I go with.

Re: 2.73's and a big stall
 

Don't worry about gears in an auto. You can make you it all by the stall.

Re: 2.73's and a big stall
 

I think i'm leaning towards the 4200/2.7str with my TR230/224 cam and *GASP* 2.73 gears! The Yank 2800/3.0str isn't enough stall for this cam by any means!
