496Ci Short Block Build Up Valve Springs
496Ci Short Block Build Up Valve Springs
Slamming the valves shut on our “almost 500” engine are COMP’s dual valvesprings, PN 944-16. When the valves are closed, the springs feature 190 pounds of pressure when installed at 1.950, but Mulvey opted to install them at 1.900, which stiffened them to 235 pounds. With a nice spring rate of 743 lb/in, it made them perfect for our 6,700-rpm stormer. View Related Article
