Why are you ordering an aftermarket intake? The pro's that were racing Pontiacs and winning (HO Racing) have flow tested factory versus many aftermarket aluminum intakes and found that the factory flowed better and produced more power through a wider range. I would look elsewhere to spend money imho

Ditto the last comment. Unless you're really stepping up peformance by changing carb, cam and exhaust, you won't realize a big gain by simply adding a high flow intake. In fact, if you're not careful, you could really hurt your driveability and peformance.

Those aftermarket intakes are often time designed for high rpm flow and aren't always efficient at off idle to 2 or 3 thousand rpms where pontiacs really shine. All the old goats will tell you that Pontiac motors are low rpm torque monsters. Don't try to build them like a small block Chevy. Embrace the low rpm torque.

Even though the motors are old school, the Pontiac engineers really did their homework. If you decide that you've got to have a new shiny aluminum intake, I'd consider the Edelbrock Perfomer.
