At any rate the intended effect of the spacer really only works on tbi' where air AND fuel go thru it. The idea is to atomize the fuel better to get more power out of it by turbulence of the mixture.(HC particles in the exhaust would go down a bit to.). The vortec's plenum kills off the turbulent effect before fuel is sprayed in the runners so it is not really deemed effective.
