HORSEfeathers !! .... there is NO WAY that this intake is near the Perf piece of the Performer intake.
I hope you are better at HORSES than IDing intake manifolds !
I think you need to look again my friend. This manifold was compared in Hot Rod manifold to several others. It stood toe to toe to the Edelbrock Performer. The Performer RPM outperformed it a wee bit on the upper end but the CH4B numbers were very comparable, especially at low and mid RPM levels. This manifold is usually found cheaper around swap meets and such and works well at idle and off idle acceleration. It wouldnt be my final pick on a mostly week end drag car but the Performer isnt any better.
