475-hp Blackbird???
You get LOADED Stage II heads, camshaft, pushrods, DynaTech SS longtubes/cats/Y pipe, Spec billet flywheel Install, LS1 Edit tuning, powder coated calipers/brackets on all 4 corners, painted valve covers, documentation and window stickers, warranty. The cars make anywhere from 430rwhp to 450rwhp. Seems somewhat worthwhile to me

Actually, I work with my dad designing and building structural steelwork for a gorilla habitat here in north GA, somewhere along the line we started calling it the gorilla farm.
So 450ish to the wheels??? Dang, wish I could get them to do that on mine for $6995. They won't do it on a regular WS6 though, right?

My comment came from a Blackbird owner in the special edition section.
Way to go GMMG!
Is there any way to install stuff on "less important" cars like the Firehawk or WS6, SS?

I have also always wanted to know if GMMG would ever consider upgrading a fixed number of cars such as the Firehawks, WS6 etc.. I like how they keep the numbers limited to make it more exclusive. I think they agreed to do a limited number of 35th anniversary Camaro SS a while ago? I would be first in line if they were ever agree to upgrade my 02' WS6. One can dream right?

Not there but close enough.
