Perhaps someone can lay some insight into it.

THe tag pics aren't there. I dunno what to think right now, and I wouldn't take any pic of the top of the lifter looking like the stock hydraulics as being so just yet. There are lash caps that go under the lifter and sit on top of the valve stem. Doubt GM would do it this way but anything is possible if they are solid. I wouldn't imagine GM used solid lifters, and any test motor they did use them on would't be sitting around as crate engines. Never know of course but I am thinking the tags are wrong. A pic of the cam casting number, or just telling us what the casting number is, what year motor that is supposed to be?

How is the cam flat position compared to each other, and compared to the crank position.

The 280 hp motor would require a different plenum than the 91-95 setup...or very high compression, very readical cam, and now low end power (very odd powerband compared to the other motors).

Run it and see...I wouldn't worry about lash because you will be tearing the cam carriers off if that is required.

Givin your batting average on being correct...ill wait for a credible source of the information.

That yellow tag could be from any non-highway engine. I am skeptical about the yellow tag only because it could be from any number of engines that require off-road use only.

I will just toss that warning tag away and say that the engine is a normal crate engine. Being such a universal engine and if this engine were the super DOHC I doubt the EPA will let it pass onto a consumer or distributer for that matter, but who knows. This would make the engine non-street legal universal fit engine, kind of hard to believe.
