I've done over 20 of them that way without a problem.
Exactly what Gomer said, and I might have said the same on the phone
Piece of wood over the pulley to be sure you aren't going to bend it any. And GENTLY tap it on until you can use your old bolt to pull it the rest of the way on. Then put on your new bolt.

Do you NEED it? MAYBE not, but with the horror stories you read here it might not be a bad idea unless your one of the people that does a bunch of installs. The pulley is an interference fit so it does NOT just slide right on. It has to convinced to go home. Once the pulley is halfway home the longer bolt is moot, but it's those first few mms of travel when you only have one or two threads of purchase that can make a big difference. GM has a special tool just for this job and the threaded rod is an even better idea than the longer bolt.

The Gm tool basically is a threaded rod., but has an attachment to space out the head of the nut so you can turn it with a wrench while holding the head with a socket
Kent Moore J41478 is the rod + nut
Kent Moore J41665 is the spacing apparatus
Also, to get proper torque you can use K M J42386-A. This bolts in place of the starter and positively locks the flywheel so you can crank the front bolt on.
Of course you can do it a bunch of other ways, I have before, but this is the right way.
