Is it worth to port both the upper and lower Cobra intakes, or just do the lower (no power adders, AFR165 58cc heads Comp XE264 cam)?
I want to keep the Cobra intake, since it's original. I'm not so much concerned with power above 6,000 RPM...sounds like TMoss-ed Cobra intake is the best way for midrange street power.
just the lower is all that is really necessary for the AFR 165s and gains will be across the rpm band.
