We contracted DOC Race to build our requirements into this great new design for the 335 and 135. They are local to us and have done a fantastic job for us on this and on other projects. This new manifold version has nearly equal length runners and is much easier to build. It also keeps the DME happy because the front and rear banks are kept separate. We will be getting this on the car right away and results will be coming soon.
