One for the transmission guys.
I have this torque converter that was in a TH 400. Any way to identify?
Looks like the tape measure moved on me, it is app. 9 3/4" across.

It was in a BOP Turbo 400 with bolts and lock nuts to hold it to the flexplate.
It is quite a bit smaller than a stock converter. I think it may have to do with racing.
I googled the #'s and came up with an empty sack.

Its for sure a racing app it has a nitrous plate on the front. stall can be anywhere from 2800 to 4000 stall. Are you selling it ? Btw it does not need the threaded lugs to be a specific bop converter . my 3000 stall has the same ring with the threaded bolt holes and mates just fone to my flex plate. i bought my converter for a gm th350 . this one might use nuts and bolts which i think is much better.

Evidently it is a serious violation to ever put any ID marks whatsoever on a damn torque converter. I wonder how the factory kept 'em straight? Inked PN marks that later came off? I have yet to ever see a clue on a factory unit, let alone a modified one. Why is it ok, std practice, pretty much REQUIRED to stamp a crank when you modify it [grind it] but never any clue at all on a TC???
I understand you can't just put a "stall speed number" on there due to application variations, but damn there ought to be SOME method of citing the internal setup.

I'm guessing this model by the description. 2500-2900 stall

Hmmm, low stall, could be, here are a few stamps I missed.
3rd pic shows 9.93. 2nd, L2. 1st pic shows where there may have been a manufacturer's sticker.

Adam, if you give the guys @ TS a call with the serial # they can give you the exact spec's on the converter. Below is a generic chart to help determine applications... Also, I believe Jeg's uses TS for their in house converters.
Jeg's #60429 Street/Strip
GM TH350/400/Powerglide XHD 10" Converter
Stall Speed: 2900-3200 RPM
Turbo Spline Input Shaft

All of the aftermarket converters I have used personally; Coan, TCI, ATI, Hughes, Trans King, and Trans Specialties code the stator type, fin angle, and clearance in the serial number that is stamped on the unit. Simply call the mfg for the specs of a specific unit and compatibility with the desired combination.
