Factory Converters

Engine ................ Diameter ............. Stall-Rate
* 225 ...................... 10.75" ................ 1450 to 1650
* 273 ...................... 10.75" ................ 1800
* 318 ...................... 10.75" ................ 1750 to 1950
* 340 ...................... 10.75" ................ 2250 to 2450
* 383 {2-Barrel} ...... 11.75" ................ 1850 to 2150
* 383 {4-Barrel} ...... 10.75" ................ 2350 to 2650
* 440 {4-Barrel} ...... 11.75" ................ 2000 to 2350
* 426 {Street Hemi} . 10.75" ................ 2650 to 2850

According to 'Mopar Guru' Tom Hoover, the Torque-Converter
from the 383 {2-Barrel} in the 1970 C-Body Station Wagons
was the loosest unit.
 
Good to know.
Anyone have an idea as what is done to a reman convertor?
Do they actually cut it apart & make repairs?
Or do they just give them a flush?

And this should make you shake your head when people say they "just bought a 2500 convertor for their moderate or hot built Mopar" or when you hear people say a 3,000 stall is "terrible on the street".
 
What about the converters that have "High Stall" inked on the body? Are they included in the above info?

As "reman" goes they are supposed to cut them open and replace the bushings and needle bearings.
They are also supposed to weld a new pump drive hub, and check/replace flexplate bolt areas.

Who knows if they actually do it.
 
So where should I be with the following in my 72 E body:

1. 318 lower end
2. 360 heads
3. 904 automatic
4. 3.23 rear
5. 14” wheels, but will soon want 17” aluminum Al classic industries wheels
 
I'm absolutely positive that some 318 2bbl's came with a 2150 stall in 904's. I've personally had some that would stall that high, and I had a mopar service book that professed it also. I cannot produce the info at the moment, but I this is true

318-Will-Run,

My information has the 318 {2-Barrel} from 1968 thru 1974 at what
I posted above.

That same 10.75" Converter, will have a Stall-Rate of 2100 RPM's in a
383 {2-Barrel}.

You will see some varied 'Stall-Rates' and other information on Mopar
Torque Converters.

Some guys state that the 440-6 {Six-Barrel and Six-Pack} came thru with
a 2300 RPM Stall-Rate with a 'Lock-Up Converter'.

Others will state that the {A-731} Converter was used on all '3' 440 engine
versions;
* 440/350 HP
* 440/375 HP
* 440/390 HP
 
I have one of those factory high stall 340 converters on my shelf.
 
Factory Converters

The 1962 {413's}, 1963 {426's} and 1964 {426's} with the 'Maximum Performance'
packages came thru with;

Diameter .............. Stall Rate
* 11.75" ............. 2100 to 2300

In mid-1964 the 'new' 426 Race Hemi came out with the 10.75"
'High-Stall' Torque-Converters, with a rated Stall-Rate of 2800 RPM's.
 
There are not just "one range" of converters for Mopars. There were factory high stalls and factory low stalls. They were stamped as such.

Paul did you compile both into that one chart? That's what it appears. Good info. Thanks.

Rusty,

Yes, this a 'combined list'.

Trying to find the exact specifications for the 273 {4-Barrel} Torque-Converter.
That converter had a 'wider' Ring Gear.

One listing had it at a 1950 to 2150 Stall-Rate, with a little bit higher 'Stall-Rate'
than the standard 273 {2-Barrel} Converter.

The Chrysler Secret Book lists the Torque-Converters as
* Low-Stall
* Standard
* High-Stall {+400 RPM over 'standard' stall-rate}

Neato. Thanks Paul. You got all kinda info.
 
Peek-A-Choo'

* 1968 ~ 383 'HP' Torque Converter
#2801764 ...... {10.75"} ..... 2350 to 2650 - Stall-Rate

* 1968 ~ 440 'HP' Torque-Converter
#2801541 ...... {11.75"} .... 2000 to 2200 - Stall-Rate

* 1968 ~ 426 'Street Hemi' Torque-Converter
#2801766 ...... {10.75"} .... 2650 to 2850 - Stall Rate
 
Can the 2801764 383 TQ be used in a small block 727?

Yes,

Just match up the 'Spline Teeth'. 1967 and up came thru with a '24-Spline'

This Converter {A-905 and A-862} was used for the
* 340
* 360
* 383 Road Runner
* 383 Super Bee
* 426 'Street Hemi' {But with an 8-Bolt Flex-Plate and '4' larger {7/16"}
Torque-Converter bolts.}
 
is there a way to identify converters, I got one with a project car, it has a picture of a lighthouse stamped on it , I figured is is a remanufactured converter, but how to know stall rate? thanks for all the great info
 
Here is how you identify your stall: 1) hold the brake firmly. 2) slowly press into the Xcelerator while holding the brakes. 3) whatever the tach says before the back tire starts to spin is your stall rating. :D Seriously, each convertor will react differently according to the torque the motor is producing. For instance, a 318 2bbl may only stall up to 1800 in Denver, Colo. Drive the same car without changing anything to the middle of Iowa, and it may stall up to 2000 rpm's. Why? The altitude in Colo will rob low end torque. Put a 360 in front of a 318 904/converter and it may stall to 2300.
 
are there any stampings or id numbers on converters? , or where they are located , good info on how to test stall on converter,
