Depending on the car, some LT1's had iron heads and some had aluminum heads. Mine has alum heads.
NO LT4'S HAD IRON HEADS, SO THEY SHOULD NOT BE HEAVIER THAN AN IRON HEADED LT1.. almost all gen1/2 sbc are 575 lb 598 with iron intake over 1000 lb not a chance.. not even a big block.. untill you fully dress it.. and with iron everything.. tops 1000 lb

Your list as set up is kind of deficient in denoting the differences in the engine families... for instance you make no distinction between iron and aluminum heads in the 60* category. Also the LX9 3500 doesn't fit in with the other LZ/LG 'High Value' engines as it doesn't share the same VVT architecture...
The 3800, or Buick V6 as you listed it also has some significant changes between Series I and II... the LN3, LG7, L27 and the Series 1 L67 don't share the same block with the L32 and Series II L67.
Here is a reference for the LX9 3500, which will be essentially the same for all non-VVT aluminum head 60* V6 engines.(2.8MPFI/3.1MPFI/3100/3400) Official LX9 Weigh-in
No alternator, power steering or A/C = 340lbs.
362 lb - GM 60 Degreee V6 OHV N/A Gen 1 (L44, LB6, LB8, LH0, L32) 340 lb - GM 60 Degreee V6 OHV N/A Gen 2/3 (LH0, L82, LG8, LA1, LX9) <- Note there were RWD/FWD versions of the LH0
The 3.4DOHC is about 465lb, that is with all accessories. Not 500lbs, Dennis. Weight Differences Thread
Me too! I have both and I haven't weighed them but the N* has three more cams. Since they are both aluminum, how can the N* be lighter?
The LS4 I weighed was fully dressed except for the power steering pump, wiring harness, and computer. There were some pretty hefty cast iron brackets used on this engine that were still on it when I weighed it, and I'm sure that helped tip the scales a bit. I did weigh some of these components individually...
That's right. I forgot about the alternator mount on the ls4. It is a massive cast iron piece. I always wondered why they didn't just cast it out of aluminum.

Where did that 3800SC info come from? Wikipedia said a L36 (3800 series 2 N/A) is 392lbs, does the supercharger, brackets, and heavier (beefier) internals really add up to that much more weight?

50lbs really isn't all that much, and going from a plastic intake to a bunch of metal on top, makes a fairly big difference.

you give me the details, and I'll add them to the list.

The Eaton supercharger, LIM , pulley, Belt are not light. Probably easily add 50 lbs.

I love parts book engineering. A book is not an engine.

I haven't weighed all of these components, and I don't intend to any time soon, as I have too much to do to take the time.
These are my estimates:
starter: 10 (gear reduction starter) alt 11 p/s pump 0 (not used) brackets 20 (engine mount and accessory mount brackets) headers 10 each (single wall fabricated stainless steel manifolds) intake and efi 10 (nylon manifold) a/c compressor 22 (seems high) water pump, 0 additional (Included with the engine on the palet)

I have my doubts that the LX9 weighs the same as the other high value motors. it should weigh in closer to the Gen III 60*V6. if I had to guess, I would say the rest of the high value engines would be a tick heavier.
