Avs 4640s carb

[44o gts dart]

How hard is it to get a 1969 avs 4640S (750 cfm ) running good enough for a 450 hp 440 )

Not a problem.
Buy a book on tuning the Carters
They were 375 HP stock and a bit underrated.
Only a cam change and headers away from well over 400 HP!

The 4640 has the tall pri jets, stock is 101, only fit AVS. Sec jets were 95, same jets as Edel carbs.

That is a real good Carb. Watch for them all the time.

Trickiest part is figuring out Metering rod tuning if you
have never worked on them
