Adam C. 2 Posted March 11, 2018 The best I can tell from finding the stamp while sorting through my pile. Ford 3L54 PB OW3 323C Tried digging around on the interwebs and the heat treated guide. Wanna start moving into the known steel world and not just half assing it with unknown. Thanks for any information! ~Adam Quote Share this post Link to post Share on other sites
