Streetmaster 318 vs. Performer for street use


I think this is the street dominator they are comparing to the street master.
A smaller open plenum with narrow runners giving more low end torque and more higher end rpm power.

The short runners are good for rpm and the fact that they are narrow gives increased torque.

The one you show is supposed to make more torque from what I've read.

I think.......not sure

And is it worth it if you already have a streetmaster. To switch it out for thevdominatir if you want increased fuel economy. I just want to drive it caring less about how much power it has.
