Thanks Donnie. Converter is in the car now - so when I get the car back home from the mechanic's house, who is doing the work for me, I'll see what pictures I can come up with
I believe from what I remember the trans is from a 1970 or 71 Impala (from the trans code on the side of the case). Also the shifter lever is for a column shifter - we are swapping that out this week for one for a floor shifter. |

If the converter is still from the Impala, it's not going to work with the L78 cam, as you are aware of. You'll need a converter to match the application, with a higher "stall" speed, either a rebuilt original or an aftermarket tuned to the cam.

Thanks Mitch. Yes you're right. I need a converter that will let the engine idle higher in gear - but I don't want a real high stall converter either. I enjoy the Pure Stock Muscle Car Drags and would need a converter that wouldn't blow-off F-70-14 tires.
But if I understand correctly - the stock converter did let the engine idle at about 750 rpm's and had a 2,200? rpm stall |

Yes,as that's what my L-78 TH-400 transmission lets it idle at.

Thanks for the info on the transmission. Right now the trans seems fine, I'll know more soon as the car is getting close to being drivable

And the new Disc Brake Hold Off Valve leaks ..... so I've ordered another one
The transmission in my car has a "CR" code with a black tag - no picture, but the torque converter only has 3 bolts. |

The 3 lug converter indicates a low-horse option...

That's what I was thinking - but no way to know IF the trans has been up-graded without taking it apart, and I don't plan to just do that with the trans working good.
But the converter has to be changed |
