Is this the part number for the LS2 90mm TB. #12570790.
I found it at GM parts direct for $214. Seems like a good buy.

I was wondering if this is a direct bolt on or do i need to do some modification to get it to mount to the LS6 manifold. Same bolt pattern???

Also, I have complete bolt-on mods along with an X1 cam and am currently making about 430rwhp. Anybody have proven dyno gains they can share. What can I expect.
