LT1 Opti SUCKS!!!!!!!!!!!
IMHO the opti is one of the best mechanical distributors ever made. What other distributer can determine cam and crank position to the 1/360 degree of a turn? Yes its in an inconvenient location but there is a reason for and its called direct coupling as to avoid slop as a result of right angle gears like a conventional SBC distributor.
When it works right, it works very well. The only "worst" thing is with the 92-94 optis that do not have venting to remove captured moisture.

I hope that when my opti replacement is complete that I will think the same. As of before, the car ran like a 2.8 v-6. I have heard how great they run, so I hope so.
Are you trying to take off the balancer or the hub? You could take the hub off, but the bolt needs to be out of the center.
If you are just taking off the balancer and it's being stubborn you might try to use a long screw driver wedged between the balancer and the three hub fingers to get it started. Also, when you put it back together clean the inside of the balancer with sand paper and do the same to the hub. A little bit of clearance goes a long ways and if you're planning on keep the car plan on replacing the optispark every 2 to 3 years.

YOU DON'T HAVE TO REMOVE THE HUB. Jesus Christ the shitty advice on these forums.
Take the 3 bolts out of the pulley. Take a rubber mallet & tap the back edges of the pulley (work your way around) & the pulley should eventually come off. You only have to remove the pulley NOT the hub to change the opti. No puller required.

You should be able to pull the crank pulley off by hand if you wigglie it good. The hub on the other hand can not be takin off by a regular puller because you need to get a really long bolt so your not just pushing on the hub. You will end up breaking the ears off the hub. Ask me how I know
