To accomplish this you would need to:
1. Alter the <prefix>_newblocks table, increasing the size of the 'title' column. I believe VARCHAR DB fields are limited to 255 characters.
2. Modify /kernel/block.php
change this line:
$this->initVar('title', XOBJ_DTYPE_TXTBOX, null, false, 150);
Replace the '150' with the new size of your field.
Then you would have to do the same thing with the <prefix>_modules, this time with the 'name' field
The file to modify for modules is /kernel/module.php
$this->initVar('name', XOBJ_DTYPE_TXTBOX, null, false, 150);
