Edelbrock carb adjustment

A 440 AVS? One of my favorite carbs!
yup just like the holley 6160 vac secondary carb that Holley build for that application Works grate! for what it is intended for.
I don't mind them AVS's but would still choose the list 6160 holley over the avs.

Now if i had to choose from a standard 1850 Holley and a AVS........well...... that would be a toss up.

The simple fact that the more "racing oriented" you get, The more the Holley become the "favorite" carb. not saying you can't make any carb work right on your ride. you can, including some of the most odd ball carbs like that funky square carb. seen some fast cars running them.
