Default Ls1 engine weight

I've read that the LS1 with auto flywheel and accessories is 457# and 465# with std flywheel. Does anybody know what the same configuration weighs in a 350 iron block/heads?

I have (out of Hot Rod magazine) 457 for auto and 497 for manual, but I've been challanged on those #s before...

Does the stock flywheel really weigh 20 lbs?

I found this site Engine Weights It shows the cast iron SBC at: Chevy small block V8 575(generic for '60s-'70s motors). After I posted my question, I got to digging around in my stack of reference crap and found a printed copy of this page. If anyone has any more accurate info, please post it.

I watched hotrod tv(back a long time ago) and it said the weigh of an LS1 but I cant remember.... I think it said the bare block weighs 175.

I know they did save 60# by going with an aluminum block, but I wasn't sure of the complete package. Actually, I'm still not sure as I don't know what is on the engine at a quoted weight.
