Port-o-sonic or Holley Street Dominator?

I would use the Hol St Dom intake. The Port O Sonic is a race intake. The St Dom is a street intake. The original rpm range quoted for the HSD was 0-5500 rpm, though I have seen this changed recently to 0-6000......for the same intake. I have used the HSD on a few different brand engines & all performed well & as advertised. It would be a good choice with the cam you have chosen.
