I can't answer your questions, but I have a question of my own: WHY?

What GT says is spot on with how to set it up. Also about the fuel injection with individual throttle bodies.
We went for the tripple webers for 2 reasons:
1. Efficiency of airflow (we don't care much about fuel consumption). The original manifold is designed to have a torquey mid-range to drag around a full size sedan. By replacing the manifold with the side drafts the airflow gets a straight shot at the inlet valve.
2. Cost. I bought a set of tripple 45mm webers (with hot 179 & M20) for $1200. I'd love to go efi with individual throttle bodies and aftermarket computer. The reality is that the efi computer would cost me probably $1200 alone, if not more.
Seriously for the street, have a look at Ed ma61's project. Don't run carbies. I only did it for the specific reasons above.

well my mind was just thinking things up  , i thought it would allow for easier fuel/air adjustment, get rid of the AFM and help simplify the fuel system, plus it would just sound cool  any info on the indivudal throttle bodies/EFI project would be nice

You could acheive all of the above with a standalone fuel/ignition ECU, while retaining the drivability and fuel economy of EFI. Don't be fooled into thinking carbies are easy to tune; a programmable ECU is far easier!

if you decided to tamper with the motor to this degree what chance has the car got of ever returning to road after you cop a defect notice? - if this car is for the street and it is to be legal how are you going to make it legal?

Obviously, it would take a lot of work.
The plan would be to not cop a defect by not being conspicuous. Multi throttles make rather a lot of induction noise at wide open throttle (as Norbie can testify!) so you really would want to use an air box for the street.

Yeah, ya noisy bastard! Of course the 3" side pipe might have had something to do with that.
