I have a 1967 GM 400 switch pitch transmission with the Kenny Bell converter. I’m having a hard time with the governor underneath wide-open throttle. I tried different combinations of governors and it still doesn’t wanna shift under wide-open throttle. It just keeps on revving and have to back pedal it for it to shift. Any Ideas
OK, then the governor calibration is at fault. What does "tried different combinations of governors" mean? Did you change the weights, grind on them, use random governors that you had lying around? Did it ever shift WOT? What happened to the original governor, or did you modify that? Governors are cheap enough. https://www.transmissionpartsusa.com/TH400_transmission_governor_p/460-000046890.htm I would buy a new one, install that, and it should shift at WOT. Then modify it from there with the B&M shift point modification kit. Change ONE thing at a time. One other thing you can try is to pull the kickdown electrical connection off of the transmission and road test the car. That will make the transmission shift lower at WOT than it would connected.
I had a couple extra governors. I tried grinding on them off per chart chain springs even took out the original stage one governor out of my stage one car. My last attempt was a governor that had the same waits as a stage1 governor but I had some lighter Springs now it’s shifting at 6k Thank you for all your info.
