I have a 1988 Monte Carlo SS with a stock 200r4 transmission and converter does anyone knows the stock converter stall speed?Thanks
200r4 stock stall converter

Just had my 87 442 converter upgraded, guy at the shop said those were the best of the stock converters out there… I believe he said they were 2200 stock however I didn’t see anything in writing.
‘All the stall’ should be the word IMHO.
Most old school people equate high stall to a slip, but that’s not the case. A quality converter with 3000 stall will act just the same as a 2000 stall when cruising at 1500-2500 rpm’s, unless the converter is a piece of crap.
My converter will stall to 3900 easily, but will cruise at 60-80mph with zero slip at cruising throttle position. And that’s pulling a trailer. I will say, at initial take off from a stop it revs up to 2000-2200 to get rolling. But once I’m going 5 mph it acts like a low stall at light throttle. And even at mild throttle, it won’t slip.
EDIT : I forgot to mention that converter diameter makes a large difference in slip as well. For most of us that street drive, a small diameter converter (8-9”) is not street friendly. A stock diameter converter is what you want.

The amount of torque the engine produces effects convertor stall speed.
Weight and final gear ratio as well.
According to a post on MontecarloSS.com forum:
I've seen some GM documentation on the D5 somewhere. Just can't recall where nor what it said. The fact is, converters are made better nowadays, and if you get a 22-2400 stall for your street engine, it will be super-driveable and should cause no issues.

I've heard all sorts of ranges to this question. But if you go to Autozone , and Oreilly's , Advance Auto Parts, and look up a replacement converter for 1987 Monti Carlo SS............It gives you a High Stall, 2025 rpm. The non SS shows 1400 I think.
GM was in the car business back then, and finicky drivers, along with GM, wanted more MPG than hole shots and planting tires so the factory stall speeds built-in were pretty conservative, but the D5 converters were pretty good for factory junk and still maintain a "lockup" as well. About the best from both worlds. I still maintain if you want something that will wake up a stocker on the street just bump up the advertised stall speed on a stock diameter torque converter. To keep from getting too warm requiring an external cooler, don't get a super-high stall speed unit, something in the low to mid 2000 range with 3.23 or deeper gears should work superbly. I'd even say you could bump it to mid to higher 2000 range depending on gearing. Variables always play the part.
