The way to exactly tell is if you send a birds eye view photo of the push rod cup. We can then determine the ratio of these rockers. However generally speaking rockers which come with push rods are likely to be 1.98:1 rockers.
Is there any way to tell what ratio your rockers are as I have pulled out a set of rockers from my mate’sengine and want to know what ratio they are?It has crow cam push rods 7.050" long and .080
