An LS7 with transmission is anywhere from 450-550# + fluids. This includes typical accessories.

On Dec 29, 2003 we discovered this page on the Chevrolet website (it has since gone away - this is why we like to make screenshots and host this data on our own site). It shows the "total dressed engine weight" of 457 pound (auto) to 497 lbs (manual) of the LS1 engine. Wow, the LS1 manual trans' "dual mass" flywheel is 40 pounds heavier than the automatic's flexplate! (this is why we encourage LS1 owners to opt for an aluminum flywheel when class rules and/or budgets allow) We don't know if that's with accessories or not. We will still weigh our dressed LS1 when we get one.
Also, note the engine block weight of 107.1 lbs - within 2% of our measurement. LS1 heads are shown to weigh 20.3 pounds each, the composite LS1 intake is 15.9 pounds, etc. Good tech, straight from the source!

A 4g63 longblock (block, internals, heads) is ~230 from what I'm finding. Add in the manifolds, turbo, and a transmission and I bet you're nearing 300-400#... so the aluminum Chevy's are definitely a #/hp winner...
Now, the 4 banger boxer motor, I'm not finding weights on those.
http://www.funco-motorsports.com/motor_weights.htm shows that the LS1 is 480 and a 2.5l subie motor is 285-320# (depending on turbo/intercooled or not). So about 200# difference. I'd assume (potentially wrongly) that the 2.0 is in the same range here.
So for 200# you're going to NOT take the 300HP?
But yes, you'll want to likely strengthen the front spring rate a bit... but having read a LOT about swaps (240z, Miata, 911's etc... you know the cars that need more powah!), it's typically not been as bad as what you're stating since the COG with the SBC typically is moved back, helping to offset any increase in weight of the drivetrain.

still, sbc is a dead winner over anything suby makes. dont have to worry about cracking pistons or blowing head gaskets or spinning bearings. plus you can always mod it for more
Well the lsx is not immune to issues either... oil starvation being the biggest issue. I'm not a subie nuthugger, but every motor has it's issues. Transplanting another motor into another brand of vehicle is rarely easy... but ya, I think $ for $ the SBC is the proven winner of that game...
Saw a company selling those stupid covers at SEMA this year. Couldn't believe that people were actually at that booth.
