I was wondering what the application is for the Victor series intakes from Edelbrock. My 340 is .030 over,.474 lift cam,(approx.) Has Eddy RPM heads with an RPM intake and a 650 EVS carb. What is the Victor series manifolds designed for? I'm about to get a 750 carb. And am considering trying a Victor 340. Either Proform er QFI carb. Would I get more HP? The rpm is a dual plane. The Victor is a single plane. What is the actual difference in performance? Thanx. R/T
