(Old F--t, Huh)

I read in another thread that you run a Howard's Hydraulic roller, do you still use your crane rockers with the Hydraulic roller cam ? I apologize.. not trying to hijack.

Earliest engine being run since 2004. Just my experience. Last edited by Chargerfan68; 09/03/20 07:23 PM. 1.50 60Ft. , 10.75@ 127MPH Hauling 3900 LBS.
