Old School 318 intake

It really depends what your using it for. Gearing, vehicle weight, mileage or performance, etc.

All the one's mentioned earlier are good manifold's. The Performer is the most current. If I was looking for a performance only intake with some cam & gear, i'd love to have a LD4B. They're not cheap though on the open market.

If your're looking for a milder, cruiser, driver style engine......The SP2P is a great manifold. Not easy to find these days, but it has great torque and pulls to 5000 r's in most applications.

I have one I got from a good member here, and i'm holding on to it for a future project if I need it.
