Look at it this way, with a stock cam, an aftermarket performance aluminum intake is just able to get more air into the engine right? But if you don't have a cam to match it, the total performance gains if the intake will be limited by the stock cam.

On the mild 350 in my Nova I noticed good seat of the pants difference between the stock iron intake with a qjet to a Edelbrock performer with a holley. But in my case I'm running a factory L-79 cam (from the 350hp/327) so it's a little more aggressive than the stock cams that came in most of them. The 350 ran well with the iron intake and q-jet, but it woke UP with the performer and the holley.


I'd say if the cam is stock, swapping to a performance aluminum intake isn't going to gain you all that much.
