Now Brett will work his magic.. with this process we enlarge the plenum and shorten the runner..
Almost All mods Lengthen the runner on the plenum floor for best results on a single plane like that. Yours will want that too. Huge plenum short runners equals slow port velocity. Bad for fuel atomization and cylinder fill.
Lengthen runner on the floor would be the worst thing you could do on an engine like this.
Maybe on low RPM stuff that could work I just don't have that answer I don't really work with low RPM stuff.
The stuff I am doing with this intake is not a guess at what will work I have a bunch of dyno and track data with intakes for high HP high RPM wedge head engines.
