Parts place has w-30 intakes yes they are a lot of cash . Has any one seen them up close for quality like port size, core shift , runner size? thanks

 

it is virtually identical to a stock W30 manifold which is identical to an iron manifold except made out of aluminum, doesn't flow any different just 40lbs lighter.

 

I had read That they flow as you stated the same and iron for factory w-30
yet lighter Im glad to hear the the repo's are good pieces . Have been told by both miller and mondello that a w-30 intake on good heads both ported will ,make in the low 500 range with a good cam you know the drill . Mondello said they like the performer with a cut down base better I thought a w-30 with a small plate to raise the butterflies out of plenum would be better???
