Son-of-a-!#%^& Clutch not disengaging
I went to test my car on the stands today and my clutch is not letting go. I have a billet steel flywheel and a after market clutch/pressure plate. My linkages are maxed out also. Could it be that my clutch pivot is not long enough? I went looking around and the longest one I could find is a 1.5 inch so I ordered it. To bad I have to take the trans out to put it in. any ideas?

The pivot is the most likely culprit. If your fork is not bent and you're still using the diaphragm type clutch, the aftermarket stuff hosed the geometery and the clutch won't release. A longer pivot should be the thing.

Justin, SpeedDirect (supporting vendor) has a kit that will give you more adjustment then the stock. Here is the URl - https://cmc.speeddirect.com/AMAZING/...%2D125&eq=&Tp=
All you need is the clutch fork to Z-Bar piece. Don't know if they would sell it seperat but it is worth a try. Better then pulling everything back out!

For that price I think I will just pull the drive shaft and slide the trans back a bit. 
Doesn't really need to come all the way out just a couple inches back to get at the ball. So will this 1.5 incher work or am I going to be screwed?

Hopefully in your case the linkage is the problem. Probably so because you have it maxed out. I have seen the Bubba solution on some trucks when the clutch sticks and its not pretty.

Factory belhousing, throwout bearing came with the cluctch ,seems
like you would be good to go, there is more then one length for
throwout bearings. seems like to short throw out bearing would not give enough adjustment to ever release the clutch.

No, meant when the clutch face sticks to the flywheel. Seen it happen on clutch replacements in a couple of trucks right after you fire it up. But Bubba pushes the truck back against a tree, wraps a chain around the tree and the bumper, jumps in and fires it up. It breaks the friction bond between the flywheel and the clutch disc and burns the surface just a hair so the clutch comes free. Years ago I watched an old guy do it and I kept thinking something is gonna give. I wanna watch this $%^!. But it worked, I dont think that is the case here since he changed all the guts out. I agree that its probably a linkage/pivot problem.

I was looking on summit and all I sw for my application was 1 1/8 inches. I sure hope that this pivot is longer and solves my problem since I would like to complete this little project.

Why are you having this trouble. You did match the new parts to the old ones didn`t you. That would be the first thing to check. I`m sure you didn`t, but do you have the disc in backwards? Most V8`s use the short bearing. the long one is primarily for 6 cylinders. and flat diaphragm pressure plates. The short bearing goes with the bent cone pressure plates.

diaphragm came with the throwout bearing, all the rest of the stuff came from different people. Were there any differences in clutch forks ?? Bellhousing is a factory 621.

Another spot to look would be the flywheel. The less expensive billet flywheels are usually Ram flywheels. They require a springless disk or the springs will push against the center of the flywheel. Result: chutch won't disengage. Solution: change to springless disk or change to standard configuration flywheel.
