Do a little research, the LSx (x being variant) is a well thought out, modern design as well. Aluminum block and cylinder heads in a compact design with large displacement.
Basically why the engine is swapped so much over offerings by other companies. It is compact, reliable, and lightweight.
FA20 dry supposedly weighs 377 lbs based off a thread I found on ft86club.
LS1, there are multiple quotes depending on where you look.... but fully dressed with oil around 430 according to hot rod magazine.
