Carb advice

[RD73Scamp]

Hi need some advice.
I have a 1973 318 with 904 transmission, Headers, Holley street dominator intake, currently running an Edelbrock 1406 (600 CFM) that I need to replace and was considering moving to the Edelbrock 1906 (650 CFM).

I will be upgrading the ignition soon and will also be changing out my rear 7 1/4 with 2:73 gears to something better and deeper.

Will the 650 CFM be too big of a carb?

the AVS 2 would be a great carb for that application.

I would endorse that 100%.

Thanks - Edelbrock tech support recommended the 500 CFM instead of the 650… for a “snappier” build. But my concern is losing the top end…

The Edelbrock carburetors are MUCH easier to tune "down" than to tune "up" if that makes sense.

Edelbrock tech support is on full retard.
