When i bought my 1999 camaro z28 in feb 2007, the previous owner had just replaced the engine a month or two before. Recently I've been upgrading my car and have found out that the engine is a little different from the original 1999 ls1 that was installed. More specifically, I discovered this when I was trying to install a harmonic balancer. Upon feeling around I found that the stock crank pulley that's currently installed does not have a key and I was unable to remove it with the tools I had. I was just wondering if anyone could help to identify exactly what kind of model LS1 mine was replaced with. I have all the original documents of the install from the previous owner if that helps at all.
Thanks in advance for any help!

LS1 crank snouts are not keyed to the balancer.

Yhea no key on the crank snout. You should be able to pull it off with a puller thats what I did. A three armed puller.
