it was some what difficult with the block out...

it is located front rigth corner (pass side front) int he first freeze plug hole.
right in fornt of the engine mount

ill post a pic of it as i have on the is out of my old engine.

coolant will have to be drained.

best way to it is through the pass wheel well with tire removed, CAC pipe as well.

Thanks for the input! I am haveing the engine rebuilt right now and i dont know if he is going to replace that under the cost or not. So if not i am going to have him go ahead and do it now while the engine is out. I just figured if it was easy then i would wait and do it myself!
