Did you even read my post comparing the prices for the two options? Listed prices for everything. I even over figured the EFI stuff.
If you buy a motor complete like the OP stated he was doing then DIY rework the harness with relays $100 bucks, add a fuel pump/lines for $100-150 and then you just need a $150 tune. So for $400 bucks you have running EFI!! To lazy to rework the harness Most place will do this for $250-$300 bucks. So for $600 bucks you have EFI same as a carb.
Its not cheaper to run EITHER one! They are pretty much the same price and more expensive for a carb conversion if you have the EFI parts alreaady when you buy the motor which is most times. Now there is a recoup value of reselling the EFI parts which would off set some of the costs but most times.
Now on the Hot Rod article link I suspect they were on the right track with nozzle angle but they only used 30lb hr injectors. That would have left alot on the table with the L92 heads, it they were duty cycled out or close ,which they probable were at that hp. It might have peaked up with 40lb'ers and more tuning. But it was a magazine article and those are setup for max power not everyday use.
Depends on what you plan to do with a vehicle. In my opinion, carbs work in ideal weather conditions. Obiously, there are rarely 'ideal' conditions present. This leaves you to change jets and tune your carburetor to the changing weather conditions as the day goes on if looking for max power like at the track. On the other hand, EFI systems automatically compensate for changing conditions and even elevations.
As for the argument that carbs make more power over port injection because the fuel helps "cool" the intake manifold. If this were true, what about Throttle Body Injection? EDIT: And if OAT's are 100* or even 80* there is no way a Venturi inside the carb is going to drop temps IAT 80 or 100*!!! It's thermodynamically impossible. Especially with a carb mounted on a steel or AL intake on a internal combustion heat engine.
Its not the runners that drops temps! And it's not a "chemical intercooler" it's the venturi (inside the Carb) that does this. Google venturi effect!!! As air moves through the carb venturi it compressed and expands and there is a temperature drop. Now it will drop some but not enough to effect performance in car engine!
The Venturi effect does happen to effect performance negatively though. One example pistons aircraft engine carb's have this problem. The carb will ice if conditions are right it could even be a 60* day if its little humid. The TB will ice at the blades as the venturi lowers temps as the humid air expanses through it and the water condenses on the blades and freezes even at 60* OAT. They have a setting for carb heat to stop this. They are not mounted on the engine, to use engine radiant heat to help lessen this so its is a problem on those motors. :End EDIT
A carburetor can not do what most EFI system's can do compared by cost. Of which I have shown the cost of both.
I take little stock in magazine articles all they are good for is selling magazines!
