Roller Rockers

[DYNO360]

Has anyone used the Crane Roller Rockers on a small block (360) circle track engine? Did you have any good or bad results. The reason I ask is the cost of the ductile iron adjustable rockers and shafts is about the same as the aluminum roller rocers, so I am thinking of going with the Crane rockers if there is an advantage.

DYNO,

I used the Crane rockers for several seasons on our limited late model before switching to W2s/Norris rockers. I ran them on solid lift cams with no trouble. Just make sure that you use the correct length pushrods-you don't want too much of the adjusting stud sticking out of the rocker-they want to break if too many threads are showing.

Been using the MP ,Crane aluminum roller rockers, (shaft lubricated) , for 3 years now on our R3 motor. Even our engine builder has been impressed. 1:6 ratio, all original, make sure you get the hex head polylocks, not the screw driver slot type.

I also use the MP alum. roller rockers. Keep swapping the rockers and shafts between engines! Love'em!
