What motor is this?

Im pretty sure now that it does have DOD this is what the valley tray looks like. http://ww2.justanswer.com/uploads/xs...195532_1-2.gif

That being said is a dod delete easy or even necessary?

I've heard that it's not too hard. Just a little more $ than a normal cam swap. This is just what I've heard. I have no first hand knowledge.

Also, what year did they make DBC TB's with DOD? That is new to me. I thought all the DOD motors came with DBW TB's.

Also, with that hole in the center of the oil pan, I'd put my money on it being from an Envoy Denali. Unless the SSR's were AWD, I think that "hole" is for the front shaft on the Envoy's and Trailblazers. Any thoughts on this theory?

DOD is deleted by simply pulling the heads, changing lifter trays, lifters, and the valley cover.

Do you have to delete it if your not going to use it? Or what is the reason to?

It can be tuned out, but those DOD lifters are JUNK JUNK JUNK. For 200$ you can delete it and have the peace of mind of having good parts.

So I tore it down today and it was DOD. Can I use the 8 good lifters and just replace the 8 DOD ones? The lifters have metal all the way around the roller like the Ls7 ones. The motor only has 10k on it so everything is very new.

You could, but for the price of a set, I'd just replace them all.
