ok i have a 360 with new rebuild.i have a collapsed lifter.this is the second time now the first one took the cam with it,i dont know if this one did or not yet.does anyone know why this is happening.i have summit 8601 cam and lifters,crane energizer roller rockers and crane pushrods.the first time this happend i called summit and they told me the valve springs in my edelbrock heads were to stiff.they matched all the numbers and sold me a new cam,lifters,and valve springs,that were supposed to match eachother.the pushrod length i believe to be correct the tip of the roller rides dead center of the valve.i dont know what else to do. i am thinking of going solid cam and lifters any ideas.
