Edelbrock Thunder Series AVS 650

IDK where the extra 50 cfm comes in on the carb. Could be the secondary side set up?

I like the AVS carb over the AFB in a big way. Though it should be known I'm talking about the OE equipment. It all still holds water IMO. The secondary sides tunable spring is a great thing IMO and you'll like it alot.

Because you can delay the opening of the secondary side unlike the AFB, you'll not have the secondary opening bog and more constant torque.

Your gonna like it.
