I have a mildly built Datsun spirit L28 and I run DCOE 40's with 32mm chokes. My jetting is based on a 40mm carb, so I cannot comment on how the 45's would take to my setup.
Your settings are the critical ones for getting the car running for sure. Idle jet, air corrector, main jet and Emulsion tube. Those the largest tuning knobs outside of just picking a carb (40 or 45 DCOE) and picking a choke size (30, 32, 34, 36, 38, etc)
However, lets us take a step back. You own a street car I assume and this is a back up for a race engine, which means those settings may be great for a race engine but not for a street engine. The difference is actually quite important. A street engine spends a lot of time at idle and even more time in the midrange were you want a good amount of torque and response. Off idle response and the transistion from idle jets to the mains is a vitally important for a street car. Now for a race, car what matters is peak HP/torque and quite a lot of time is spent Wide Open Throttle (WOT). Idle quality, efficiency, smooth transition are not nearly as important. A weber is a wonderful thing. It can be tuned to hit many critical areas. But it usually has to compromise somewhere. Be mindful of the difference between a street engine and a race engine. A race engine will not be happy living in daily traffic. I would think that those settings will make lots of power, but may not produce a happy street car.
