Hello All

I have a 64 with the TH400 transmission and I need to replace the o-ring on the electrical case connector due to a small leak. Does anyone know the right size replacement? The o-ring with the red box around it is the one I am trying to figure out the size for and the FSM does not provide details for the O-ring size.

The previous owner used two green (A/C?) O-rings to seal it, plus some type of RTV, and it didn't work.

Any suggestions? Seems like this connector is a 64 only part for the TH400 so I haven't been able to find much online.

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
