Re: Ramhorns vs. Headers for MPG gains?

For mileage, I have always run an Edelbrock SP-2P manifold. They were sold in the 70s as a mileage manifold. You can find them on Ebay most any time pretty cheap. They have small runners for increased velocity of the fuel/ air charge. Super off idle performance too.
