X3 on the Holley Street Avenger 770cfm. I pulled a Carter Comp Plus AFB 625cfm off and popped the 770 on and the motor ran smoother, the carb adjusted very well, and the motor loves it.
I was concerned the 770cfm would be too much for my 383, but was pleasantly surprised.
If you have a good flowing exhaust setup and a decent intake, the bigger carbs will work, but there is a mileage penalty. You are getting away from the cruiser mode. Might as well stick a hotter cam in it to take advantage of the better breathing characteristics! ![](/ubbthreads/images/graemlins/Twocents.gif)
