    Super Sucker or Open spacer

    The motor is a 406 w/ 18* heads. The intake has a "turtle" in it. What would be the best or is hard to say without trying both to see if there is anything noticable?

    Lots will depend on whether you need more torque or more topend.

        SuperSucker will give you more torque,a 4 hole will give you even more torque and the open spacer will give you more topend.

          Depends on your engine...When we got our engine, I called and asked the builder, Bill H what would be the best deal and he said with our SB2 engine that a 2" open spacer gave the best numbers on the dyno...It was wanting more open plenum area obviously...
