On paper it looks like a good off the shelf manifold for my 427 sbc. With it’s larger plenum and thinned divider walls should be less restrictive to my cylinder head flow. But I hope the added cost over the Super Victor pays off in HP and TQ. The casting quality seems to be perfect being many companies are still suffering thru employee shortages. The cnc 1206 gasket match could’ve gone further into the runner than it’s 3/8” it is now. But I blended it into the runner about 3” using a 60grit cartridge roll. Dyno time soon
