455 to 425 th400 swap?

The switch pitch was a type of early lock-up torque converter and trans. Olds used it on the turbo 400 from 65 to 67. On the throttle linkage under the hood near firewall there is a switch mechanism that controls the switch pitch and also kickdown for passing gear I believe. The factory shop manual has info about the switch pitch.....maybe others can elaborate on this.

Everyday I learn
something new about the 'Olds' world. Being a traditional 'bowtie' guy from birth, I was sheltered from this wonderful invention.
I also was smart and bought a factory service manual for 67 Olds. Here is the information from that publication:
"The stator control solenoid is activated from a switch in the throttle linkage at engine idle which changes the stator blade angle (pitch)from low to high. It is also energized at 40 degrees and over of carburator opening by a switch in the throttle linkage to change the stator blades from low angle to high angle."
Hope this helps others, it did me.
