Port-o-sonic or Holley Street Dominator?

That’s true. The difference between the two intakes is small on low power builds. When you twist the screws to the intake and push the power levels way up, that’s where you find the difference.

I used the chink knock off on my sons ‘91 4X4 dodge with Edelbrock heads and carb. The cam is the small thumper. I’m not taxing the intakes potential. If I have the cam another 30* in duration, ported heads, etc….. I’m sure we would see something.
