What I have is:

FFR MKII Cobra Replica
FoMoCo 345HP crate motor
GT40X heads
B303 cam
GT40 shorty headers
TFS Street Heat
BBK 70MM TB
GMS 30lb MAF
30lb injectors

What I need is:

EGR delete (to keep the TB in the right spot?)
TB
Plumbing

What my thought was:

Reuse the GMS MAF sensor and install it on a CNL 76mm setup
Install a new TB that will better match the TFS Street Heat. I am thinking 75mm Accufab with a blank spacer. Basically what TFS suggested.

None of this is assembled. The existing warmed over 5.0 has the GMS 30lb MAF, and BBK 70MM TB and EGR plate, along with a polished HO intake. I plan on getting everything together for an engine swap sometime this summer.

I sure am open to observations/ideas/uncontrolled laughter.......

only thing you'll really need in the name of fuel is a better pump. i've got a built 347 and i'm running 30lb inj and a 255fuel pump. but i'm gonna have to say ditch that intake. very restrictive, at least get a gt40 off a cobra or explorer.
