Slant 6 4bbl Carb Selection

Is this the cable you’re talking about?
Yes there are other manufactures out there too. Spectre is another. Also Bouchillon Performance
just buy a new Eddy AVS2 500
The AVS2 is a superior up graded carb over the Edelbrock Performer. If you are buying new.
And like Rusty said the 1407 is a 750 CFM.
