Clutch stuck in Muncie 4 speed 65 Malibu SS? Tips/Tricks?

[Gasbuggy]

Imagine my surprise when I start this car up on a 4-post lift and it wants to take off. (Emergency brake was on lightly, fortunately) . My 65 sat for just a little 2 months in a humid space, and it seems that my clutch plate is stuck to the flywheel. To me, that's only a problem for cars sitting for years. The clutch pedal, Z Bar, etc seem to be working fine. I tried trick #1, try to start the car in 4th gear. The starter couldn't budge it.

Not running, you can put the car in any gear. There were no issues with the throwout bearing or anything mechanical. I'm not sure of the brand but the transmission has a blow proof bellhousing and a purple aftermarket clutch assembly, does not have many miles on it. My next idea was to put it in first, not running, have someone sit in car the with the clutch depressed while a few of us rock the it back and forth, I'm hoping the driveline slack banging back and forth might break it free. Some say to jack the car up and start it in 2nd gear, and hit the gas then brakes or warm the car up in neutral then restart in gear and drive it until it breaks loose.

I suppose there could be something else wrong. I'm open to suggestions.

Start it up with the rear up on a jack and a person in the car with the clutch and brakes depressed and drop it off the jack quickly?

Just spitballing here. That idea might well end up in a shower of sparks and broken dreams.

Quite a few years ago, I had an Opel GT and the pilot shaft bearing failed while sitting at a traffic light. With the clutch depressed, it just started moving forward. The bearing seized the pilot shaft, so the clutch/throwout bearing was no longer effective. Took some serious leverage to get the tranny out.

Pressure plate likely seized on the trans input shaft splines and-or seized in the pilot bushing. Put it in neutral, start the engine and let it heat up. Maybe a few heat cycles could free it up. A blow proof bellhousing typically has to be blueprinted upon installation to ensure proper alignment. If that wasn’t done you may have issues related to misaligned trans. You posted so here’s an opinion…find a factory bellhousing, a decent stock clutch assembly (not Zoom or Centerforce), and replace that blow proof bellhousing. They cause more trouble than they’re worth.
