Torque Converter Stall Speed help.

DMC_78 said
Looking for advice on selecting the correct converter for my build. It’s actually going into a 78 Dodge D100 truck… but I come here for all the great tech information.

Combo is a 5.9 mag with good EQ heads, 9.4 compression, Hughes 218/222 hydraulic roller and 750 vac secondary carb.

Tranny is a A500 that I am currently rebuilding with a OD unit from a 518 with the newer gear set. Gearing out back is 3.91’s.

Looking for recommendations on stall speed and where to get a good converter built. I want a tight one that will stall when the gas is mashed, but will still drive good in town. I am looking to keep things lock up.

Open to ideas!

Thanks for your help.

I'm running a stroked 5.9 Magnum with a Precision of New Hampton 3800 stall 3 disc lock-up converter into a Stage 2 Extreme Automatic's 2004R. The lock-up feature can only be activated in 4th gear, and their high quality converter is very efficient. It only drops about 350 rpm between the locked and un-locked position on the freeway.

My point is that buying a quality converter and opting for the lock-up feature is worth pursuing.

I just ordered another converter from Circle D Converters for another combo. Not cheap, but great customer service and reputation.
