I have a 67 Corvette with a 350 and I have an Edelbrock intake manifold labeled C3BY. I want to replace it with a polished aluminum intake and I have been told the only Edelbrock to fit under the hood is the Torker II. I can't find any info on the C3BY manifold I have to compare it to the Torker II....as I am concerned that I will lose power by making this change. Can anyone help with the spec's on the current manifold I have?? Thx!
