414 Dyno results: Missed combo?

If you could get the higher tq numbers to start at 2800, you'd never
have to downshift with a 4:10 maybe a 3:91 gear on the street.
I'm not sure if a smaller venturie carb would speed up the airflow
and feed the cylinders more across the rpm range.
From the airflow numbers it never drew more than 600cfm and max tq
was at 512cfm.
Just a curious thought to see if was overcarbed.
