The glittery specks is bearing material. Have the crank turned, new bearings and good as new. Assuming you didn't hurt anything spinning a rod bearing, I've seen them cause a lot of damage but not everyone. How long did you run it after it picked up the noise?

Any chance of details on this "upcoming project"?

Good luck with everything.

i didnt run it after.. just got it into my drive way and had it sit for days until i had time.

Well the project now depends on the condition of this motor... if its still salvageable then rebuild and drop it into this 2001 trans am firebird i picked up.. thinkin about boosting it.
