The iron block itself weighs ~154 lbs. With the rotating assembly installed, you are looking at another ~70 lbs. It depends what crank you are using, some of the forged cranks will weight less than the stock crank, some will weigh more. The stock 4.6 3.543 nodular iron crank is roughly 51 lbs.
The shortblock will be no more than 235 lbs MAX.
oh i plan on having some help. even if i could do it im not trying to kill myself and get a hernia.
if it weighs 300 or less we can move it around, but if its like 500 then i will make other arrangements to get it to the shop.
so, you guys think a couple of guys can move that thing around?
It won't weigh anymore than stock. Only by going with an aluminum block are you going to see a reduction in weight.
That being said, I've got no idea what the "short block" would weight, but an iron block 4.6L fully dressed (the way it would sit in your engine bay, with all the accesories) weights right in at just about 500lbs....give or take. An aluminum block 4.6L like an Explorer engine would clock in at about 80lbs lighter.
We're talking the difference of a couple of pounds here....nothing significant from a dry weight perspective. The over all weight between the two is still essentially the same. It’s true that heavier internal components (rods mainly) will soak up a little horsepower due to the added centrifugal inertia, but most people making the kind of power necessary for use of a forged bottom end aren't really all that concerned with the loss of a few horsepower vs. the cost of replacing the short block if you were to grenade it under load.Yes a built block weighs more all the parts are bigger and heavier. A stock shortblock will make more power also because the rotating assembly weighs less. That's with all mods being the same. There reason you have built shortblock is for toughness.
Mine weighed 250 by the manifest.

thanks guys. as long as i can move it with a friend, il be ok. at the weight of 250 we should be ok.
also if i happen to loose a couple of hp because of forged internals, i think the stroker i got will more then make up for it.
