How much does the CTS-V LSA V-8 engine from the current CTS-V weigh, including supercharger?

I haven't seen any published numbers on it, but I'd guess about 550lb dressed. Also depends on whether you include the intercooler plumbing and heat exchanger, and in MT form the dual-mass flywheels tend to be quite heavy.

Haven't looked in a while but there was some good info on GM engines in the powertrian section on Gm's website.

For your entertainment, the 2009 GM LSA marine engine.

467lb but that's without the automotive front-dress, flywheel or flexplate, and intercooler heat-exchanger, pump, etc. so I'd say my 550lb estimate's still looking good for an as-installed weight.

This one is too easy!

1) Buy a ZR1, a CTS-V & an M5.
2) Pull the engines from each.
3) Weigh engines.
4) Write down results.
5) Reassmble cars.
6) Ship them to me for disposal.

No idea on exact weights of LS9 or LSA. :crying2:
