About White Owl Speed
White Owl Speed brings you the high-quality combination you want. For example, White Owl Speed's competitors are limited to Chrysler's 413-440 base, a complete set of competition manifolds designed to meet your special needs. These combinations have been tested and proven to outperform other so-called top products, not only attractive to professionals but also to those who need the best-performing products that can be bought anywhere. In order to get the maximum performance from the OFFENHAUSER turbo thrust manifold, it is very important not to modify the top in any way! The reason for this recommendation is that after hundreds of hours of testing on various types of flow systems, they finally determined the design included in the device.
