identifying torque converter?
I had a falling out with this guys that was suppose to work on my car, and I'm not absolutely certian that he installed the "2400 stall" converter that he claims. I didn't feel any difference in drivibg the car. Is there any easy way to tell what converter the car is using? or whether he even changed it?
Stall test
Do a Stall test. Make sure sure you have good brakes and good tires or you'll end up spinning tires.
Pull parking brake and put one foot on the brake pedal while you put the other foot on the gas pedal. The max RPMs your engine will accelerate to without moving is your stall speed.
The car shouldnt move at all during this test and don't do this for more than 5 seconds!

Not really. The stock ones Ive seen so far have a sticker listing the part number on the front of the TC, but itll be near impossible to read with the TC still in the car. Maybe unbolt the TC and slide it back as far as itll go. Might be able to read it.

H-Bomb is right. The key is not to do it for too long like he said. Once it breakes lose and moves ahead a foot or so, the test is over. Keep and eye on the tach.

Re: identifying torque converter?
Like they said, the stall test is the way to go. If the engine doesnt get above at least 2000 rpm, then you dont have the 2400 rpm stall TC in there. The stock one stalls at something like 1600 rpm, although, behind my 350, it stalled at around 1800+.
