Hey guys long story short my buddy has a dodge van he got a new converter for his transmisson, but we think it has a lot more stall than it should I dunno if they mix matched parts at the shop or what also it’s suppose to be for a 75 360 I only see a little plate welded on it I thought there was suppose to be a bigger weight,
 
A 1975 360 will have a converter with a large triangular weight welded between two of the mounting pads. How are you determining that it has more stall speed than it should?
 
That’s the only spot that has a weight on it.

My buddy is saying that it doesn’t move unless he revs up a lot, and feels a loss of power when flooring it, this was after getting a new convertor
 
To act like what you are describing the converter would either have to be extremely modified or badly damaged, unless your trans is starting off in a higher gear instead of first. You should have noticed a bad enough engine shake to make the stall speed seem secondary if you installed a non weighted converter in that 360.
 
Nice palm, but what does the other half of the converter look like? The weight will usually be opposite the drain plug on these earlier converters.
 
That tiny weight is just to balance the converter. A 360 has a weight or weights on the front to imbalance it where the drain plug would be; sometimes two weights on either side of the drain plug. Pic of the other front half of the converter...I bet your fluid is low; check in NEUTRAL.
 
He’s said there is no weight on the front, only on the inside in the picture above.

so that should show that this torque converter is not for a 360 engine? Also I looked up the part number it says the stall speed is 2100-2400

He said that there is no weights at all only on the other side, I dunno why he sent me half a picture lol there is no triangle weight he needs that special flex plate,
 
Yes, you could use the B&M flexplate for the 360 and that would solve the balance problem but not the increased stall speed issue. I would consider purchasing the correct converter for the application and using the one you have for something not requiring a weight but needing the increased stall speed.

So you think the advertised stall speed of 2100-2400 if too much for a van? I was thinking the 1800-2200 would work better since it’s heavy
 
If the engine has sufficient torque the stall speed in the 1600-1800 range would pull better gear to gear and reduce transmission temps. If you have a hotter than stock cam and just use the Van to bomb around in, the increased stall speed would give you more oompf off the line and increase the fun factor but would build more heat.

Okay after doing research that is the incorrect torque converter and stall speed for a stock van the correct one has that huge weight on front and a mush lower stall speed Thanks a lot guys!!

Sure he didn't break the ears off of the pump in the trans putting it all together? I made that mistake as a kid and it did exactly what you are describing.

I don’t think so, but I’ll ask him to check! The part number of that torque converter show it’s not balanced and it’s 2100-2400 stall, the actual torque converter that’s listed for his van has a lower stall and the triangle weight welded on it, I think the trans shop just gave him what ever they had.

Converter for a '75 360: 12", narrow ring gear. Stall 1900-2200, two weights welded on the front side(engine side) of converter:L 1.62" x .75" x .380"
Converter for a '75 360: 11", wide ring gear. Stall 2000-2300, two weights, again welded on the engine side of the converter. Same as above.
Hope this helps.
Stall speed can vary.
