No they don't replace displacement. A 200 cubic inch ricer on 25 pounds of boost is nothing compared to a 500 inch V8 on 25 pounds of boost. Those ricers also do not produce any where near the torque a big inch V8 does. The upside to running a ricer is weight of the drive train, smaller tires so less rotating mass and usually the ricer cars are shit boxes weighing about 1500 pounds. If those ricer engines were they way to go everyone from Pro Mod up would be running them instead of 500 inch Hemis.
Bigger is always better.
