Yes, there is a special tool. If you look on Ebay you can pick it up for about $10. I would be careful here, you don't want to damage the machining on the crank or the block.

too bad ls1howto didn't mention that it is needed.

Not all 3 jaw pullers are created equal. If you have a friend to hold the jaws in place while you tighten it, that may help. If not, use another puller.

There is a tool for that as well, and it also will double for the front pulley.

Just for ***** and giggles, When I took the stock one off, I had to cut the bitch on one side. it was hard as hell. Then when I did my second cam swap, I already had the double roller on it and that one came of easily!
