Those mopars are torquey , shifting at only 4,800-5,000 rpm. Maybe, 2.76-3.23 is all thats needed with 215/60/15's turning. Stick with velocity and go performer(non-rpm) intake. You can't skip up past 2000rpm with clutch or stall. A RPM would decrease the low end. You need that Performers 1500 rpm push to be ready, sucking air, and strong. Its Pulling with the crank throws, made to rev up from idle-2,200.
