so i was changing my optispark on my lt1 and when I went to bolt it back up, I broke the bolt, the bolt is now stuck way in there and I can barely see it, What should i do?

You might be able to remove the timing cover and get ahold of what's left of the bolt.

Is there a certain way to do it or not do it?

You're going to want to lower the oil pan enough to get the cover out. Unsure if this can be done with the motor bolted to the mounts (assuming you have an F body?). I haven't wrenched on an F body since the mid '90s.
Pull the crank hub, remove the rest of the bolts on the cover and slide it off. Be very careful with the oil pan seal.

Plenty of vids & forum posts out there showing/describing the procedure.

An easy out might get it done too - depends on how badly the broken bolt is stuck...
