408 ignition curver advice

How do the venturi and throttle bore sizes compare between the 850 and 950 you've tried? I've found that 850 carbs usually have larger venturis and maybe larger throttle bores than some 950s.

I will check, don't recall off top of my head. Both Quick Fuel carbs, both Q model, one 850, one 950. Both jetted and tuned on dyno.
