Replacing my 1 bbl over to a 2bbl. Need help!

I’ve always liked the principal of a large two barrel carburetor on a \6 better than a four barrel. The smaller plenum/stronger vacuum signal and the larger bores and venturis of a 2300 Holley would work well together. Fuel thirsty but simple. At one time, there was a 650 CFM two barrel NASCAR version available.
