Old SB intake manifolds

The Wieand Action Plus is a good intake and can carry you into some really quick time slips. Power production from this intake should not be a problem at all.

To block the heat cross over from the head into the intake, use a piece of aluminum cut to size and at about a thickness that will not make sealing the intake a issue. Thinner than .050 is fine. Slightly bigger than the hole to cover and silicone it to be sure.
