Ls1 factory rocker arm strength for max spring pressure. Dose anyone know or have information on what spring pressure the factory ls1 rocker arms can handle and at what rpm range please.
I'm looking at 470lb open pressure and 7500rpm limit.
Just not sure on the strength of powdered metal rocker arms.
Thanks in advance.

Would like to stay with factory rocker arms and just do a trunion upgrade.
Much cheaper option to roller rockers.
But im concerned about the 7500 rpm range with 470lb spring pressure and 620 lift cam.
My lifters are good for upto 535lb. So no issues there.
