Intake manifold question

Edelbrock makes a Performer Street intake for the 318 A. If I remember correctly, its for $209 bucks and the rpm range max on it is 5500. Its a 4-barrel intake.

If you are looking for ones off a different engine, You are gonna have to look for another polysphere 318. or another polysphere with a similar intake pattern. But finding a polysphere engine thats not a 318 is difficult. Poly parts are hard to find. even for the 318, but those engines are absolute torque monsters!
