I have ran Wilson Manifolds in other applications and their work is some of the best seen and raced.I am not sure how well their new Cummins manifold will work but if their past has shown me anything its they do not go into a project and expect it to fail.Wilson Manifolds power some of the nations fastest Superstock,Comp Eliminator and Pro Stock cars in the country.It will be a part that many will watch and see how it helps or doesn't help.Too bad they did not make one for us early motor owners.......Andy
