Holley Street Avenger 770 for 408?

I've got a street Avenger 670 carburetor. I haven't rejetted it since I took it out of the box. The only adjustments I've made are to the idle screws based on readings from a vacuum gauge.

I originally bought this for a 302 Ford in a 66 fairlane. Worked great. Great driveability.

Put it on the stock 318 in my Dart (when I installed an LD4B). Also worked great. Great driveability, the manifold and carb really helped out the 318.

Put it on my cammed up 5.9 and reset the idle mixture. Works great. I intend to tune it more thoroughly on this car, but it almost drives like an injected car right now.

With the electric chokes you have to remember not to leave the key on without the engine running for long periods of time. The choke relies on the engine drawing air through the choke to cool the spring.

I've found that the choke requires adjusting based on what time of year it is. For the summer months, I just set it to come off as quickly as possible and that's always worked for me.
