CHINO, CA – December 20, 2022 – (Motor Sports NewsWire) – Camshafts are the heart of any engine and is where tuning started for us. In 1954 Pop Yoshimura was grinding cams by hand. A lot of time has passed since then, one thing has not…passion. Today, Yoshimura cams are created in Japan from a special steel alloy billet and is just what the CP2 engine needs to make more grunt.
