Torque converter ID help

[justavillain]

I tore my blown motor out and need a new torque converter ... Well maybe unless someone knows what the slip is on this.

I don't have any idea or seen any other marks on it. It's a 727 and mated to a 440.

Excellent post,I think. 11-12” TC, maybe 15-1800 stall for stock? Can’t remember the stock stuff. Too many years, but this might get pretty interesting.

Is there anything I missed that I can check on?

Edit it is about 12" wide

call a torque convert rebuild shop , or a tranny shop they d know right away

It's a CR10 oem converter.

be carefull. that writing could mean it has been rebuilt using an old housing. take it to a rebuilder and let them take it apart, or just get a new one. just trying to say the #'s may not be correct for what is inside.

Any weights on the back of it, if so what are the dimensions of them? From the factory, it should have two weights on it as the 440(from the factory) has a forged crank in it. It definitely has been rebuilt as the factory OEM converters are not painted. The CR-10 converter is for the 225 leaning tower of power and the 318 with a 727. They have no weights welded to the back. The CR10 also has two different thickness mounting pads: Thick ones from 1972 to 1976, and thin ones from 1977-up. The stenciled number H768 may mean that it has been modified(the H may stand for High stall), but unless you take it to a converter rebuilding shop, you'll never really know. Your typical transmission shop probably won't know and would send it to his converter supplier to have it ID'd. Hope this is of some help.
Or you could be really lucky and find out it's a HEMI converter(1967 to 1990).

Forged crank = no weights, internally balanced.
Cast crank = weighted balancer and flywheel/TC

All cast cranks had weights, different styles and different weights. And yup, no reading glasses on at the time, 440 from the factory was the cast crank. My bad.

Prior to 1972 440 cranks were forged

It was a factory 383 car and changed to a 440 by the previous owner. No weights on the face. No drain either.

If you had a known stock converter you can just compare the welds
I've seen painted oem transmission maybe even a green on in a 66 Imperial
most any trans shop should be able to tell if it's a rebuilt
what did it stall with the 440?
this is for a blown motor
you want at least brazed fins and roller bearings and whatever stall you think you need
if a roots blower you will have more torque so any given converter will stall higher
or is this a blown motor like you kicked a rod?
also remember that early motors had different size input shaft
for those of you with small shaft swap out to a later pump and shaft there is a reason Ma Mopar upgraded and converters are more widely available

It's blown as in the cam broke and tore up the block. She was a big block 4 cyl for about 3 miles.... I never had it running right so I cannot say for sure what it was.

The previous owner said it was a 3k stall....but he said a lot of things and so far nothing except this car being a Superbee and it having a 383 per the Vin are correct. Everything else he said has been way off or flat out wrong. If it was rebuilt they ground the welds off perfectly. One shop thinks it's a 440 correct high stall oem non-lockup so about 2600 he said. That I could believe since it would be close to the 3k I was told.

Photos of the block..... It is sad to see this block go to the scraper....

so what's your new powerplant going to be?
might as well give it a try
nice to have a baseline if you have to change you know which way to jump and how high (or your converter guy will)
sorry about your loss
