How would this do with my set-up? I figure that I'd have to have injector bosses drilled for the truck injectors. An intake elbow from intakeelbows.com and some kind of bracket for the throttlebody cables. Then maybe upgrade to a 90mm throttle body.

My main concern is gaining alot of top-end without loosing a bunch of low end. I could manage loosing a tiny bit, but not enough to where it would bog during daily driving. I think the rpm rating is like 1500-6000 or something. So what do ya'll think?

 

I think that there are plenty of choices for manifolds for the LSx and wouldn't bother going through the PITA to make it work.
