I'm needing a ported intake for my 97 Formy. Is there a difference in the 94-97 intakes at all? What about from the z28 to the birds?

 

dont know about difference in years, but they are the same for the Chevys and Pontiacs

 

i think the 93-95 (non vented opti) are diffrent from the vented (some 95-97)

 

i'm pretty sure the only difference in intakes is 92-93, 94-97 model yrs
the 92-93 intakes dont have a fuel crossover line like the 94-97's have, a couple inches behind the throttle body on the top of the intake, that the only difference i know of!

 

simple's right. The fuel rails' cross-over bar was located differently requiring a different manifold design in 1994.

Other than that, there's identical (except for the LT4 intake of course, which was powder-coated red and had raised runner ports).

 

Oh yeah... all platforms used the same intake for each year aswell. The Vette, Fbody, Impalla/Caprise/Fleetwood cars were all the same intake.

 

Sweet, this will make it easier for me to find a ported one.
