My job takes me into some GM facilities. Last week I was looking at some as cast blocks, before any machining work. The tag on the pallet said 3.5/3.9 L. Kinda hard to say if these are the 60 v6 blocks by looking at them before they were machined, they were destined for Tonawanda, NY. Is it likely we will have a 3900 or are these a diffrent platform.
