Default Heads and cam swap in progress, a few questions may arise

I'm finally making the jump to do the heads and cam in my car. I've gotten it torn down to the bare heads, and decided to pull the timing cover off so I could start getting new parts on.

When I got the timing cover off, there was something hanging out on the crank sprocket that I can't seem to find in any diagrams. Does anyone have any idea what this is?

do a search on crank position sensor. all it is good for is detecting a misfire and what cylinder it's coming from. the timing is done through the optispark.

96, OBD2, motors have the reluctor wheel on crank and CPS on the Timing cover. The Damper hub is shorter than 94-95 as it bottoms out on the reluctor

So from a quick search through the interwebs, it would appear that deleting it is the way to go. Would I be alright just pulling it off? Or is there something I need to put in it's place? And would I need to get it tuned out when I get my retune done?

There is no reason or advantage to delete it. You would need to get another hub (one that was used with no reluctor) or put in a spacer to take the reluctor's place. You will get trouble codes if you don't have it tuned out. On the benefit side, it will tell you when you have misfires.

Thank you. I'll just leave it in there, then. I was hoping I could just tune it out and be done with it.

your screen name suggests you have a 94....so if you do this motor was likely a transplant from a 96

If you are still OBD1 your PCM does not know the CPS (or reluctor) is there so simply removing it would not be a problem but you would need to get the longer 94-95 damper hub.

There is no problem just leaving it if you want to save $ not buying the different hub

It's a bit of a story, but it's a 96 car. I appreciate the advice though! I'm thinking about maybe getting an obd1 car in the future for a strip-only car, so I'll keep that in mind.
