i am currently experimenting with them and find this to have some basis here.
Isn't the Edelbrock Torker a relatively low rise singe plane? Wonder how it compares in torque and hp to a Performer RPM? Guess it depends on the comparative size of the ports too. Also, I think the old Tarantula sp manifold was fairly low too.
