i was just sitting here bored as ever and a thought popped in my head, its kinda dumb but.. is there any way an LT1 thottle body can fit on a 3.8?

 

no need, as the 3.8 tb is allready plenty big. you'd need some big mods to even see a difference.

 

Requires some custom fabrication, but you could do it.
I think the single-bore is more efficient though.
If I had to do all that fab work, I'd just mount a larger single tb on there.

I don't think you would gain much with stock heads/cam.
