750cfm too much?

Okay so i am in the middle of installing long tube headers on my stock 318. My neighbor gave me a Holley 750cfm dual feed and i'm planning on getting an Edelbrock Air Gap intake. Is 750 too much carb for the teen? I mean, Chrysler put thermoquads on them right?

Seems a bit much for a teen especially if it's stock compression and camshaft. I would think a 650 would be just fine. Thermoquads were different. They had small primaries and the secondaries opened when needed and only as much as needed. tmm
