Mine is currently in the car, so that is out of the question. And in having more nickle in the block, it makes the metal stronger. Therefore allowing the use of LESS metal to contruct the block and heads. If you look at them side by side, a Buick vs lets say a Chevy, the buick mains and main webbing are physically and visually smaller than that of a SBC. Also, buick never made a four bolt main block. Why? Because stock for stock, the blocks and bottom ends are stronger. Why? More nickel. Chevys made four bolt mains because their bottom ends barely held together in stock form.

Do you have pictures of the webbing or are you just posting what you found on the internet?. And to say that a Chevy two bolt block barely held together is ridiculous.

To bring some science up in here lol:

More nickel doesn't really equate to less weight, because nickel is a heavier metal than iron. The molar mass of iron is less than that of nickel, though they are very close. Like within 3g/mol of each other.

Sort of like how a 5x5x5in cube of wood weights the same as a 2x2x2in cube of lead (these arnt exact; its just so you see the point).

As far as volume is concerned, the Buick block might be smaller, but it could be more dense, i.e. heavier. I don't know what metals Buick engines consist of, and I don't know anything about Buick vs Olds vs Chevy engines etc, so I don't know how big they are relative to each other. Just thought Id share that a smaller volume of nickel can weigh the same as a larger volume of iron; it just takes up less space.

Orange one is a chevy, other is a Buick. Couldn't find a picture of my bottom end, but it is the same. They look identical, they do, but in real life side by side there is a noticeable difference. The buick would not have been touted as one of the lightest cast iron GM small blocks and lightest of the 350s for no reason.

One can be certain however, that a 350 Buick is lighter than a Chevy 350. That's the whole argument at this point.

Even though everyone is telling you otherwise, kudos for sticking to your guns about that engine weight, bro. Got to respect that.

It's because I'm right. The Buick 350 is lighter than a sbc 350. I have messed with both engines. I have built both engines. I have picked up and moved both types of blocks, heads, intakes, cranks, you name it. The Buick stuff was ALWAYS lighter weight. Except the intake. Holy crap. 67lbs is a lot.
 
At least in the case of the 350 and 455 Buick, they are the lightest of the all cast iron GM small and big block family. I do agree, the 450lb for the 350 may be wrong, but it is for certain lighter in weight than a SBC, which by most accounts is as heavy as 575lbs. A BBB is just over 600lbs, and a BBC is over 700lbs. Thin wall castings and nickle yo.
 
I don't think anyone said the Buick engine was not lighter, the Buick 350 is almost as wide as the Buick 455 so I doubt the Buick 350 is only 450 lbs.
 
I suppose along with my inspection of the innards of my 350 this spring, I shall weigh it as well. Anyone know how accurate those little S hook scales are that one would attach to an engine hoist? Engine will be full weight. Heads, intake, carb (lift plate will be on engine, but I will just lay the carb on top of the motor), manifolds, starter, alternator, P/S pump, everything. After debating this forever it really makes me curious. Then, and only then will we know if the entire internet is mistaken. OH, and I suppose when I weigh the motor, I'll know which springs to get. 😀

EDIT: Engine will be dry though. Ain't gonna have a leaky mess sitting in my garage.
EDIT #2: Or I may do it with the fluids in. I guess it depends how much I spill when taking it out.
