all i know is i ain't buying a BMR k-member. i had one break and my friends broke. to of my buddies have been running Umi and Spohn and no problems. and both umi and spohn said theres will fit like BMR.
so Spohn all the way.

I noticed in the instructions it mentions changing motor mounts. Are new mounts included in the kit? What's different about them, are they just poly mounts?

I going to say the clearance is close to the body. And you dont want a ton of flex like the stock motor mounts do. Luckly I have done all that allready

To just physically mock up a 4L80E all you would need is a cross member from Yank or BMR. To actually use it you need to have HP Tuners modify the PCM to control it, a speartech wiring harness, and a 4L80E converter with an LS1 front cover.
The only modification to the trans tunnel I did was quite a ways back, just forward of the tail shaft for the wiring harness to clear, nothing that should affect your kit.
The bell housing has some little tabs or ears on it that need to be cut off, and the bell housing itself sticks out a little past the block in a couple places (wider), but again that can be trimmed. My web host is down, I can put some pics up later.

Would a turbo 400 be a problem although if do go auto pretty sure will go 480 to keep and overdrive.

When longtube headers first came out, that's what we had to do to keep emission equipment. Just giving you an option instead casting 2 different manifolds.
