Got a good deal on a Fast 90mm intake. Stock they're worth 15hp over a ls6 and 20+ over a ls1. I need to weigh my car soon so I can calculate my rwhp based on 1/8th mile times more accurately, but it the car weighs 3650 with me in it (should be a close estimate) then I went from 325rwhp to around 360rwhp after this swap. (some of this should be better knock sensors and 8% more throttle readings).
Its a 3 piece design so I took it apart for porting and removing casting flash.

Fished it all up by painting it semi gloss black cause the primer gray plastic look was too lame looking for me.
