Never used that particular one but I like the design - certainly better than an Edelbrock Performer for an application looking for 6000+ RPM

About a month ago my grandson and I replaced the Ford aluminum manifold on the 289 in his 66 Mustang with the sbf version of that manifold. It's an engine I rebuilt in 79 and ran for a long time with a Holley 2 barrel. It now has a 600dp and Mallory dual point dizzy converted to Petronix and a Comp 268 cam, I believe, and headers and the Offy did make a difference. It's basically a single plane with a split plenum and works fine on the street.
