Is this going to be too much for a street car? I was told I need it to match my cam. But also it will build up alot of heat. I have a trans cooler and a deeper pan to help the cooling? Will that stall burn my trans up? 700 R4

i've got a 3500 in my car. the engine don't get above stall speed untill i get on the interstate. cruising aroubd town it would be alright. but i wouldn't go 300 mile trip with it. i'm sure it gets hot but if you have good cooling then you should be alright. most cams have a recommended stall. i would go with that.


HYDRAULIC: Street/ strip, 2800+ stall. Likes headers and gears, rough idle.

 

Go with a 2800-3000stall and it wont hurt to get a tranny temp guage.

 

Can I get some more input from others with this high of stall. The car is near complete, and I plan to install a trans cooler, but just want to know if anybody has temp problems...

 

I've got a 3000 RPM stall on the 700R4 in my 84. With an auxiliary cooler the temperature in the pan still stays mostly around 140-160 F. Make sure your TCC is locked in 4th and you'll be fine.

 

I have a 4,000 stall and drive around town no problem. Even when I was running a 3500 stall, the trans never got too hot driving up and down the highway and up long hills. Running a B&M trans cooler only.

 

It is also non-locking

 

Why have a 700r4 if it's not lockup ? You might as well throw a th350 in your car and be done with it.

 

It worked fine for the guy that had it in his car before me. All he did was fairly long trips and street driving.

 

i'm running an edge 3200 stall, derale tranny pan, and a painless 4th gear lockup kit in a freshly rebuilt 700.

tranny temp gauge hasn't gone above 150 driving, and 160ish at a stoplight.

trying to get used to this stall converter, i can barely tell when it shifts anymore haha. doesn't take much pedal travel to bring the revs up. motor sounds a lot healthier too.

plus i'm pushing a hair over 2 grand cruising at 55 w/ 3.42s locked up in OD. not bad IMO.

 

no lock up on long distance will hurt your wallet with fuel costs. Is the 700 modified? A good tranny cooler with a fan and you will have no issues i suspect.

 

You need to match it up with the right gear. A 3.55 or 3.73 is not enough for your motor (with a XE284H) or for a 3500stall. Get 4.10's. get a 3500stall "lock up" converter.
When the trans is in OD and locked up there will not be any heat building converter slip. Hiway cruise rpm will be very good. (about 2300rpm) with 3.55 or 3.73's the rpm will be too low. A cammed up motor does not like to cruise at a low rpm. It is just not effiecent at such a low rpm.

My car is near identical to yours. other than being a 400ci and using a th350trans. Drive it around all the time and drive it to the track with a 3500 stall and 4.10's. No trans heat problems.
if your th700r4 gives up on ya, it won't be because of the converter stall. its usually a internal hard part that fails under power.
My stock convertered th700 eventuallycame unglued. I was able to rebuild a th350 and buy a new quality 3500stall converter for much less than the cost of the th700rebuild.

With a cam that big in a 350 overdrive is near useless.
(it works but there is not fuel mileage to be gained as the motor just does not want to operate effiencently at low rpm while in OD. its much happier cruising near 3000rpm on the hiway. When the ignition and carb are set up properly the mileage is not bad.
I run the mechanical spark timing "locked out" with that XE284 cam + some vacuum advance (10-15deg) at part throttle. Cruises very nicely.
When you mismatch up a 3500stall converter with a gear that is not high enough (2.73 3.08 3.55) the car is always labouring on the converter. (the engine rpm never gets away from the rpm that the torque converter is in "stall mode" and multiplying torque. Thats where trans overheating occurs.

The higher ratio gears (4.10+) make the car very driveable with a high stall 3500 converter.
So if your car/engine combo calls for a 3500+stall don;t wimp out on the rear gear ratio.

 

I agree with what f bird is saying also. my 383 with a short cam 224 230 duration with mid 500 lift likes to cruise at 2000 minimum even with my 3.73 ratio i use overdive basically at 60mph or above or i am just getting out of the power band.( and i have also locked out my timing) so if highway long distance is not in your future skip the 4 spd auto. as mine with all the hard parts was $3000.00 certainly more than a turbo 350 tranny.

 

ah yes, I am running a 3.73 outback. This setup should not see much highway, just city driving, only a few maybe hour long trips. Just concerned about heat, only have a 4-pass fluid cooler

 

3500 is small, we run 4500 typically in most cars that we drive around. Remember that if you're just tooling around town to keep it in a lower gear where you can keep the rpms up a bit. In city driving overdrive should not even be used.

 

This will sounds a bit stupid, but I don't remember the shift pattern on the 700. I have a 4th gen console, so I don't know what gear I'm in, I just pull it back til it wants to go forward. P R N OD D 2 1. Is that how the pattern goes?
