this can't be good.
 

just finished preparing my block for installation and while it was in the air, i noticed this:

block is a lq9 408 stroker. That looks like the reluctor wheel on the crank, but i am really tired right now so maybe i'm not thinking straight. Isn't there supposed to be a plug there? that's a really big plug if so.

Crankshaft position sensor goes there.

^^^^yep, won't run without it.

wow, how did i not figure that out. I was confusing it with the camshaft sensor i just bought. Big brain fart. Now if i can just get this sob engine in the engine bay i'll be good to go.

Brain Farts happen... don't beat yourself up over it.
