Has anybody ever had a new pilot bearing that was too tight on the tranny input shaft? Or can it be too tight if it is installed? It's in a '69 350. Thanks for any help.

The most common cause of "too tight" is a burr on the input shaft or the bushing. Check to see if it is burred or if the shaft has a mushroomed end front hitting something while out. It is also easy to mushroom in the bushing when installing if you don't use an installation tool (used input shaft).
The second is alignment problems. Since you probably have no choice, pull the bellhousing, clutch, and pressure plate back off. See if the transmission will fit in the hole this way. DO NOT let the transmission hang from the input or bushing. If it does, then you may have the bellhousing out of whack.
If it won't, see if you can borrow another input shaft or transmission to see if it fits. In not, then the bushing is probably the wrong size and needs to come back out. I've known people to ream them, but they are supposed to fit when you get them.
