Stock Cobra upper and ported lower. I don't think you don't really have the heads or cam for a Holley Systemax II or Edelbrock Performer RPM II. Do a search on this over on the Corral and you will find several guys running a 347 storker with the Cobra intake. I had one and it was great up to about 5500 rpm. My new combo was too much cam and head for it so I moved up to the RPM II. You can use the RPM II with your combo but you will loose bottom end torque. TMoss is probably the most qualified on the Corral to answer this question so do a search with TMoss and Cobra intake. Should get you a bunch of reading. Another thing to consider is reving a hydraulilc roller cam over 6000 rpm. This is starting to get into the area of a solid roller cam. I know there are people out there doing it but some have had problems as well. Just something else to think about and research. Talk to the cam builders as they will let you know what intake matches your current head cam combo but don't get mad if they say to change heads or cam.
