Not Ranked
I have two sets of the Dove HD rockers (1.200” wide). with end stands. The oldest set is in a 427 that has 850 # of open spring pressure and the engine has seen 8500 RPM on the tach. I did pay close attention to the push rod length and had a custom set of manton pushrods made. No issues after 5 years. The second set is in a 427 that only truns 7200 RPM with 550 # of open spring pressure two years old, no issues. Custom manton push rods in this engine also.
