Hi Frank The Plumber; For stock, Ford and Motor's manuals. For performance and knowledge Huntington, Lawson, and Holleran. Huntington did use some other guys info but usually said so when he did and he had good science. For good science and hands on experience, Lawson and Holleran, hands down. For Bishop and Oddo, some good info but they were also promoting someone like the magazine articals do. JMO, Craig.
