The runners in the HO intakes are slightly bigger than the plane 5.0 intake.

I know the runners are both longer and bigger on the E7 manifolds over the E6 manifolds. But I thought that all the E7 manifolds were the same, Ill have to verify next time im out at the JY. As far as telling if its an HO or not, there is easier ways than removing the plate on top. If it has a 60mm TB, its the HO, also if it has yellow top injectors and a car style intake (and the engine hasnt been molested) its the HO.

Conanski's right on about the HO being cast into the upper intake. This was reseached by some members on the Ranger Power Sports V8 forum a couple years ago. The uppers look similar, but are different internally.
