Depends what you are weighing. Aluminum based LS blocks are ~100 lbs lighter than an iron block. Components such as alternator, P/S pump, water pump, intake/exhaust manifolds, intercooler, turbocharger, clutch, and flywheel can change the weight.
LS aluminum long block dressed can weigh from 425-500+ lbs with
GM parts,
LS aluminum block dressed with aftermarket parts (crank pulley, oil pan, alternator, water pump, etc.) can weigh 385-425 lbs.
LS aluminum long block weighs
~350lbs with oil pan but no accessories Correction It actually weighs 310lbs with a Sikky oil pan and crank pulley and less than 350lbs with a subaru clutch/flywheel assembly
LS aluminum short block weighs ~250lbs and that includes the cam and timing chain.
By comparison:
EJ257 DAVCS
Subaru turbo long block dressed with mid frame turbo and EWG ~350+ lbs
Subaru turbo long block dressed, stock ~325 lbs
Subaru turbo long block ~210 lbs
Subaru short block ~100 lbs
For reference a group 35 battery is 35-40lbs and a GTX3076R is ~30lbs. A front mount intercooler and pipes is roughly ~40-50lbs, stock bumper support on JDM cars is 12 lbs.
That is not a big difference when you double the amount of cylinders and more than double or triple the displacement, while keeping the whole Subaru AWD.
The EJ engine is very light in SOHC (1.8-2.5L) naturally aspirated versions, ~200-225 lbs fully dressed. The LS comes with very bulky accessories from GM but many aftermarket parts are available that considerably drop weight.
