Does it look like this?
Its a knock sensor for the ESC system, which has a computer behind the glove box to control spark and a special HEI distributor. My '84 K10 with a 305 had that setup.

Unfortunately I can't see pics being a non payee. I ditched the computer and dizzy long time ago. Wonder if I can pull this sensor and plug the hole?
If it is a knock sensor it should be a blind hole, won't really need a plug.
I thought that was open to the water jacket?
no . sbc and early bbc used water jacket drain hole for block .
Gotcha, been working with big blocks lately.
That’s a very good “problem” to have !

Ok,,,thanks.,,so if I pull that sensor , is coolant gonna come pouring out ? I'm a assuming it'll use standard 1/4" or 3/8" bung to block it ?
Yes, it will dump coolant. Catch it in a bucket and pour it back in through a paint strainer. Unless I am remembering wrong, again, it should be a standard pipe plug. I like a dab of sealant on them.
is pipe plug. Could be clogged with rust, have had to poke a few to drain some older blocks.
Leave it in and forget it . . There solid like a pipe plug already .
That's exactly what I did
