Anyone know about what the stock stall speed would be in a 71 Duster /6 car? I'm looking at one now that has a 3000 stall in it and I don't know how streetable it would be..Help would be appreciated. Rear is 3.23 8 3/4.

...the 3000 won't stall @3000 RPM behind the /6. Stock is around 18-1900 RPM, if I remember correctly. I erred on the side of caution w/ my SDsix Duster and went with a "2800" (advertised). I wish I had been less conservative, it stalls at about 2100-2200 RPM behind my six.

Stall speed for stock late '60s early '70s 225 is around 1700 to 1900. I sure wouldn't want to pay the gasoline bill after swapping in a 3000 rpm converter...nor would I want to drive such a car around town. All the slant-6's nice low-end torque would get turned into heat in the converter instead of motion down the road.

Too many people who were born on third base actually believe they've hit a triple.

Thanks for the great info.

...as I mentioned, it's not going to stall at 3000 RPM behind the /6. The 2800 RPM converter is not even noticeable behind my /6. I'm going to go with a "3000" soon or possibly even higher in my Duster. I hope to get the stall speed up around 24 -2500. When you cam one up a little, you kill a tad of that bottom end anyway. That's one reason my 60' times suck so bad...
