anyone running a 3.8L n/a torque converter?

I've got a 93' cougar 3.8L N/A parts car and I'm thinking of installing the torque converter in my 90 SC for a bit more stall speed. has anyone done this yet? does anyone have the K specs of both the converters? (both trannies are AOD)

I did this last Fall. I put a Ford 140k torque converter in my 94 SC which had a 110k converter in it from the factory. The 140k torque converter is the factory converter for all 3.8 N/A T-Birds (with the 4R70W transmission) and all 4.6 T-Birds. The swap moved my stall speed up about 400 rpm which is not a lot but it helps. My 60' went from 2.0's to 1.9's. My best 1/4 mile E.T. before the swap was 14.079. After the swap and under pretty much the same weather conditions my best 1/4 mile E.T. is 14.000. The difference is probably not all from the converter swap because I removed my full power passenger seat on the 14.000 run but I can feel the difference off the line.

I don't know the K spec's for the different AOD torque converters but you could E-mail Jerry W (Ford OD Transmissions 101 author) for the information.

I'm going for a performance rebuild on My supercoupe soon (192,000 miles on her) and With a 205/205 .477 lift cam I figured a bit more stall wouldn't hurt. I'll have to send Jerry a e-mail and see if he has the specs, I'm just looking for a 200-300rpm increase in stall speed without shelling ALOT of money out for another converter (just payed 1000$ for a multidisc PI 3000rpm converter for my 96' LX)

I will soon have a stock 3.8L N/A 4r70w converter for sale.

According to the data from Ford Thunderbird Specifications on this web site the 1993 N/A 3.8 Cougar has a 165 K factor torque converter while the 1990 SC has a 140 K.

3.8 n/a converter

Is this converter a lock up or non-lock up?

Will it fit a '92 SC?

Is it a very hard job to change them out? Does anyone have details how to change the torque converter?

What is a "K" factor?

thanks-

that ends up mathmatically being about a 300rpm gain in stall speed then over a stock SC converter. Might be worth the swap then, might as well try it, the engine will be out of the car.

go here to read about "K" and how torque converters are REALLY rated.
