Hey guys, yet another question! I was wondering what would be the best stall or best stall converter for that matter for my application? I did a quick search and came up with way too many threads! Well, i have the 700r-4 which will be "built" and i will most likely be running with 3.73s. I am dropping in the fastburn crate motor with the hot cam and i was told that i should use a 2800 stall with that cam!? The guy that is doing the tranny work for me would be getting me a 2400 stall canverter. He told me that for the street that i should not go any higher than that. Now, he does not know what motor work i am doing really and this car is not my daily driver. I can sacrafice some drivability for some power. Which stall would be best, thanks for any info and to get it out of the way already without any smartass posts, i know nothing! thanks

 

I have tried a few different stall speeds, and I have become a big fan of lots of stall. My next converter will be a 3,000 stall. As long as you get a lockup converter, streetablility is not to bad, at least I don't think so. I have yet to try a 9" converter, but they weigh a whole lot less, and I have heard that they help improve throttle response due to the less reciprocating mass. Hope this helps.

 

For best racing, you want the stall to be a little below the motor's peak torque RPM.You launch there, shift at peak HP, and if your gear ratios are right, you'll be back at peak torque after the shift. You'll go through the lights at or just beyond peak HP.

2800 RPM for your combo sounds reasonable to me, maybe a little on the low side, but who knows what the "best" would be... that's a tuning thing, that real racers work on after getting the motor and suspension working right.

Your trans guy is thinking of 2 things though... the first is, on the street, you'll be in stall mode alot of the time, which generates ALOT of heat, which is hard on a trans, so get a BIG trans fluid cooler; and he's still going to be a little worried about warrantying it. The other is that you may get real sick of your car seeming like it's at the strip every single time you come to a red light, where it doesn't move until you wind it up to 3000 RPM or whatever; it does kind of get old after a while. But with the 700s lockup, at least it won't be too bad cruising, no different then than a stock one would be.

 

Its not really that bad. I had a 2200-2500 stall converter and it would only see that much when I was hard into it. Just day to day driving, it was very reasonable.

 

Thanks for helping out! I am definately going to invest in a tranny cooler to make sure it will hold up longer! The guy already said that there is no guarantee. He told me that he would build it for me and after that it is in my hands. It all depends on how hard i drive, which will not be hard at all. It is basically my baby and i have a daily driver to beat around. He told me that there is a guy that lives near me with a 500hp hot rod backed up by a 700 and he has been running the set up for over 5 years. He told me it is all on how i drive the car. I think i will go with the 2800 for now. Which company would you really recommend? thanks

 

Why no warranty? Obviously, the builder either A) doesn't beleive in his work, or B) doesn't beleive in the parts he uses. I have beat on alot of 700's, and they have all held up great. You will find that alot of rebuilders who specialize in beefing up 700's will offer some sort of warranty.

 

I do not know why, it does seem fishy but he is well known and respected! He does a lot of race cars in my area as well! We will see though what he really has to say. I have a feeling he is one of those guys that will not waste his time on you unless you have the transmission and cash in hand! I do not even know what converter he will be using!? I'll see what he has to say when i have the tranny ready to give him. Thanks for looking out, later

 

I give warranties on all my performance 700R4 transmissions as long as they use the 9.5" lockup (Vigilante, A.C.T.) or the Continental 10" non-lockup. The 12" diameter (any stall) is hard on the driveline because of its weight and does not multiply torque as well as the 9.5" or 10" TC's. The smaller diameter TC's are about 15-17 lbs. lighter. The choice of stall depends on a lot on what the cam duration is at .050 lift, induction system, compression ratio, rear end gear ratio, type of driving, etc.

 

Pro Built, if i were to give you that info would you be able to recommend something for me? thanks for your time and info!

 

I have a 3k stall vigilante, behind a weenie 305 no less so it's relatively looser than a 3k stall behind a hot cammed 350. Actually overkill considering the stock heads and cam at this point.

Nontheless it's incredible and i can't even imagine going back to a sluggish stock converter. Completely driveable, and the gains, from launch and even simple highway speed kickdowns are perfect.

Don't let somebody talk you out of getting a nice converter. Single best bang for the buck mod you can get next to heads, maybe better.

 

Thanks Ed, you have been pretty helpful in the past too! From what everyone says you can really notice a difference with better gears and a good stall converter. Now, anyone recommend one? I know i will probally hear a lot of Vigilanties! Should i just go with them, considering the money i have into this "project", i do not want to come up short, especially on a converter! Thanks again guys, later

 

IMO you can't go wrong with a Vig or Yank. You're paying for the quality sure, but i have NEVER heard a regret from anyone buying one.

As for any of the other knock-off small diameter converters, i can't say the same thing. I just haven't seen the 60's of enough people (or ANY people for that matter) running them, so it's kind of hard to pass judgement. I'd rather pay the extra $200 for the name and KNOW that i had the best converter around rather than risk the $4-500 and find out that even though it 'works' i can't cut the short times that everyone else does.

 

Sal at A.C.T. Performance is using the Sonnax billet steel cover like Yank & others. The Vigilante & Yank are good TC's, but so is the A.C.T. Each have there own way of doing modifications for achieving stall. From what I have seen the modifications are pretty much the same. It just depends on your preferences and how much do you want to spend. 86IROCNJ, tell me what you have & I can make a recommendation as to what you will need.

 

Hey Pro Built, thanks for the offer! Alright, here is some info. The duration at .050" lift is 219 intake and 228 exhaust. The intake i will be running is the Tpis miniram for fastburn heads. The gears i plan on using will be 3.73 ratio and the compression ratio is 9.6 to 1. If you need any more info let me know. A guy using the hot cam recomended a 2800 stall for me. I will be using the car mainly on the street as well as the drag strip to get some times, nothing too serious yet! Thanks for your help-Bryan

 

All i know about ACT converters is that for all the people on these boards runing them, i don't see anybody with results with them. Just reports of being 'happy' with them. And the occasional 1.9 60' *yawn*

Maybe they're good converters, but until i see more than a few people running 1.7s and better with them behind mild combos, i'm just not convinced. From everything i've seen, you are getting a lot of value for the extra $150 for a purple friend....

 

Thanks again Ed as well as everyone! I will keep everything in mind when it comes time to do this in the next couple of weeks or so. Pro Built, whenever you get a chance! Thanks again for your time guys, later.

 

Well, i got the motor out today and probally monday i will be dropping off the trans! Can anyone else recommend which stall or stall converter i should get? Thanks again guys!

 

Pro Built, can you help me please? anyone else for that matter. would a 2800 be pretty good for my setup? It looks like i will be ordering my own converter! thanks
