I know the CAT rockers are not in the same league as T&D, Harlan Sharpe, or Jesel, but with a mild hydraulic cam and open spring pressures of maybe #350 max the cheap rockers work fine. Being really cheap you could get the 1.7:1 ratio aluminum rockers for $200.
A guy in our car club has been running them aluminum rockers on a near stock 440 for at least the last two or three years with no issues.



I'd rather not take my chances on the cheap rockers , that's funny you dropped names of the big buck rockers , I don't consider cats better than STAMPED STEEL rockers .

Your friend running them has been LUCKY , there is a very prominent member of this board that had a set of CCJ rockers fail with less than 500 miles on them , wasted his shortblock on his blown 440 , wasn't worth the few busks he saved on the rockers .
