Ok, here is the new thread.

Quick background: Bought car for daughter, knowing it had a spun main bearing.
Was going to rebuild engine, but the fellas here set me on the better choice of an engine swap: http://www.grandprixforums.net/threa...ebuild-Project
(many thanks to Buck531, ScottyDoggs, WarStryker13, and many others for setting me on the right path!)

My daughter and I will do the work together.
She gets her license later this year, so we can take our time, label things and photograph as we go.

Old Engine: L36 with spun bearing



New Engine: L26, 18k miles, long block+ (see pic below)


First question: what is that next to the EGR on the new L26 engine, but doesn't seem to be on the old L36 engine?
Do I need to keep it or toss it?
