Jeff , I sent you a PM.

But I have to agree, the work that was done to that intake in the link is on a +500" motor that needs to kill some bottom end so the tires don't go up in smoke.

If you want it to LOOK stock you could find an old M1 dual plane, it's a copy of the 666 intake only in aluminum.

The stock intake has 4 runners with acute angle turns I can't imagine how that works out well ??? but the engineers must have knew something ?
