I drive about 250ish miles a week half on the interstated for about 25 miles at a time, i have stock gears right now and am at about 2k rpm at 70ish, i want to go 410s but ive noticed everyone that posted a thread has a 5 speed, would 410's be ok for that kind of driving or should i go with the 373's. Next ? is how big of a stall for a DD? I'm doing a bunch of mods while its in the garage for the winter and i'm gonna be getting most of the mods in the near future so just looking for advice thanks

a flash stall will drive like normal and not cause any driving issues. the flash stall will only stall when pressure is brought up quickly, like from a standing start/slow roll, then just smash the pedal. true/brake stall requires pressure to be built up before it even starts to transmit the power. as for gearing, i prefer the 4.10's in an auto. the rpms will be sitting around 2800-3000 rpm's when running 70 on the hiway.

Stay away from the 4.10's in the auto. . . . unless you dont plan on trapping over 105 ever. . . .

3.73's and stall in the range of 2500-2800 will yield nice kick in the pants without crazy rpm's on the freeway.

First of all...your mileage scenario is pretty damn similar to what I was driving my Stang for last year. I got my Mustang in March of 07 and my Honda in November of 07 which is now my daily driver. There was no way in hell I was going to subject the Mustang to winter salt and last winter sucked here in central IL! For people who can afford it I recommend them getting a front wheel drive car for the winter time...yeah I could have had a supercharger for the Stang for the amount of money that I spent on my Honda but in a few years the body on the Mustang isn't going to look so good. Driving a rear wheel car in the winter is not impossible with the right kind of tires...it's the other idiots out there you got to watch for. Just couldn't allow it..or want to take my chances w/the Stang so by getting another car I decided to go with a much shorter gear ratio and higher stall torque converter than what most people would consider DD friendly?

Secondly, since this is your daily driver and a lot of miles are hw miles...from a gas standpoint you are going to save money by going with 3.73's. I can tell you that I travel the interstate at about 70 mph in the Stang and I'm running 2800 rpms...now that is w/my 4.30's. With the 3.73's you should be turning about 2400 rpms, and 2600 rpms w/4.10's at stock tire height. Not much of a difference but when you are talking hundreds of miles a month at an increase of 200 rpms you are going to use more gas. How much you REALLY save is going to depend on how you drive?

So for gears it all boils down to if you really care how much gas you are using or if you want more performance. I can tell you right now 4.10's are going to be quicker and better yet 4.30's are really going to make a difference from your 3.27's.

For stalls, don't go less than 3000 rpms. Your stock stall is rated around 2500 already. I'm going w/ a 3700 one. I already have it sitting in my house but don't have it in yet and won't be putting it in till next year, so I can't really tell you how the higher stall feels. Once you put your gears in the stock stall will act lower than what it really is because of the nature of how stalls work. The gears appear to make your car lighter which in turn makes the conveter flash sooner which gets your car moving sooner also. I can tell you that w/my 4.30's not only is the stall out of whack but it needs a tune real bad so make sure you get a tune on the transmission and get a good transmission cooler because your going to heat up the transmission fluid w/the extra slippage of a higher stall. One more thing I would like to point out is that you may want to wait on getting your stall until after you are done doing any major modification in the performance aspect of you car. Stalls are built to match current powerlevels to what they are built for. So if you are doing a bunch of performance mods that will increase horsepower by a bunch you are going to change the dynamics of how the stall works and potentially change it's stall speed too?

Hope this info helps you make a wise decision

I just noticed in your sig...your supercharged. So the 4.10's might be too much...your going to get different opinions on this but the 3.73's might be better...like smoothgrandmama said your trap speeds might be lower due to the fact that you can't use 4th gear for racing. But if it is just an all out street car then the 4.10's would be fun for 0-100 blasts...traction limited or pending of course!

Thanks, as for a winter driver i have my dads truck so i dont have to worry bout the salt and stuff, its gonna be int he garage and torn appart for the winter. As for how i drive i might do one stomp to 100 per gas tank, i'm gettin better at bein conservative but 373's are looking good. I went to the track with my current setup and trapped 106mph at 13.0 so i was just looking to drop a lil off that. As for the stall i'll look into the flash one you're talking about.

[thatdavidkid]

i would honestly think about 3.55's.... i drove a mach with 3.55's and a t-trim the other day and it pulled very hard, but still had a good amount of time in each gear... 3.73s wouldnt be too bad, but seriously, why not just bump the boost a bit, are you running an intercooler? if not, get one and run meth, and save the gear money for more power... 3.27s in a 2v car will yield about the same amount of time per gear as 3.55's in that mach... if you can get to around 500 hp, (dont know much about 2v motors, dunno if it'll hold up) you'll have an extremely fun car.

well this is all going towards my winter project, the mods in my sig will all be done at one time. so yeah i'll be running another 4-5lbs of boost prolly

[Shibby50]

and yes i'm running a 2 core intercooler it came with the procharger

I didn't mention in my other post but I see you are from Joliet...not too terribly far from me. But anyway...that's good that you have another vehicle for winter. I didn't have that luxury when I had my 91 5.0 GT back in the day. I also wasn't making much money back then so I had to wing it all year long and let me tell you...it sucked. I know there is a lot of you guys out there that have to drive their stang in the winter where it snows and most can attest it ain't fun...a few seem to think it don't matter because they run the proper tires...and just drive sensibly...but the majority would drive another car if they could...because even though you might be able to drive in it with no problems the salt is going to eat away your car and that is something you can't avoid

You are like me...I hardly ever really get on it on the street...maybe cause I'm older but some days I really drive the car like it was meant to be driven...FAST...lol. When I was younger I really drove the piss out of my 91 5.0...lol...I like to think I still haven't reached half life yet. But you know life can change in an instant so you just never know. I would say go with a 3200 at least...should work real good in getting some low 60 foot times if you can hook? I would think sticky tires would be a must with your blower and future gear and torque upgrades.

my buddy had a vortech auto with 4.10's, i thought it was about as perfect as you can get. the centri can run a shorter gear better than a positive displacement, since the torque is not poured on all at once.

what are you smoking? I trap 116 to 118 with an auto and 4:10's

good info

[Shibby50]

yeah i really dont wanna drive it in the winter but i prolly will be on the days that theres no snow. it will prolly be appoart for a few weeks as all the mods will be going in at once, i'm only 19 and dont make a whole lot but i'm savin and buyin for it all so i only have to get tuned one time. i know how bad it is drivin in the winter my last car was a 00 SS camaro and i didnt have the truck to drive. Right now i think im leanin towards a 3200 flash stall and 373's. thanks for the info so far any more opinions welcome
