Out of the ones listed - the Holley will outflow them all, then I believe it is pretty close between the TFS track heat (if that is the one you are refering to, there is a street version also) and Edelbrock RPM. The Gt-40 will flow the least. Just because it flow more doesn't mean it will make the most power for your combo. The Holley tends to be a little big for some mild combos.
