Push Rod Length? Empty Push Rod Length?

Post  powerstrokeace December 9th 2011, 8:32 pm

Guys I'm wondering By changing my rocker ratio by.03 do you think I would have to change the push rod length? Going to the 1.73 instead of the 1.70. And if I were to change cams would I have to change the length also. I know its a given to alway check it but just have to ask. I can confues my self real eary these days. scratch

If JUST changing the ratio ... probably not.
However, ratio changes also often involve changed lever lengths on both sides of the rocker arm trunion and a lot of times pushrod cup to roller tip angularity differences along with pushrod seat angle differences also. All this will usually require different length pushrods.
