Stock '68 383 exhaust upgrade??

If I was picking a carb for that mild 383 build something along the lines of a 650cfm proform street series carb would get my vote. It is available with an electric choke as well.

I'm torn between the Proform Street Series and the Edelbrock Thunder AVS carb. All I can tell is the Proform has mechanical secondaries and the AVS is vacuum actuated.  What do you like about the Proform carb?  Thanks!

I've found the Proform/Holley carbs easier to tune and are more responsive to throttle position changes. 

I also like that the fuel bowls are on the ends of the main body which helps with vapor lock. A Carter/Eddy carb holds the fuel within the main body so more heat is transferred to the fuel.

Okay I want a Proform now.

Do proform carbs have the correct kick down linkage, etc?

Ron's got me looking at the preforms too , cant make up my mind to go with one of there street carb's or go full tilt and the race item, which allows me to go upsize to the 950

Quick answer is no 

When installing a Holley/Proform style carb you need to purchase the Holley mopar throttle linkage adapter pn 20-7 and install it to the throttle lever. The kd pin can be removed from your existing carb and transferred over to the 20-7 adapter & then the kd linkage will work.

TTI with Dynomax gets my vote.
