Cliff is correct a factory iron intake can and do run well into the 9's.
Jay DeLaigle's 1974 Trans Am with his '455 FAST ENGINE' stroked to 501 cubic inches is a good example. Take note of the work performed to his intake.... 1974 Pontiac EGR cast iron intake, Ported and flowed by Wilson Manifolds with support from Jon Kasse racing engines and SD performance. Wilson Manifolds , top dogs in the intake modification industry. Pricey work I bet ! Cliff and Paul K comments are well taken, the RPM intake can shine above 500 hp.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
