Yes.
Not quite the same thing but I originally ran my Corolla on carbs and a purpose built dizzy.
It had a huge hole in the power around 5000RPM which it wouldn't accelerate through in ANY gear.
Mapped ignition at least allowed my to drive through it, throttle bodies pretty much cured.
We then played with 40mm, 42mm, 45mm and 48mm throttle bodies. 48mm gave the best power but lost little or nothing compared to the smaller bodies.
And by best I am talking 10% plus improvements (48mm compared to 42mm).
The car also starts and ticks over, which is nice.
I am on similar cam dimensions to you, but only have 400cc per cylinder.
