Budget Build 5.9 for a 71 Scamp

Ok back to the subject at hand.

Still collecting bargain parts for this build. There is a guy near me with a used Edelbrock 1406 (600cfm) carb. Electric choke. Is that enough CFM for my use?
Enough? Yes. But IMO there are much better choices. Lots of guys love the edlebroken carbs. I do NOT. If I put your combo together it would get a 3310vs Holley. All that being said, buy the carburetor YOU are most comfortable tuning. And if that’s an edlebrock get a 650avs2.
