My fathers 545 Che*y conversion included a dual fuel carb. It bolted to the stock manifold so it was a quadrajet replacement. If they do not make one for big blocks, an adapter from square bore to spreadbore is only about 20 bucks. Will a quadrajet will bolt on? It is a spreadbore carb (secondary holes larger than primary).
