Thread: 427 side oiler is possesed

Ok, here's what I have been able to find out so far... according to the current engine builder the rocker assembly is a Harlan-Sharp unit (shaft mount, likely 1.75:1 ratio) and the push rods are Crowlers. His next step is to blue up the ends of the push rods and the lifters to see how well matched they are. He's also going to confirm that the diameters are the same. He thinks that if they are of different diameter that this would induce instability and result in the push rod to move out of alignment with the rocker. I realize that is this isn't much to go on and probably not specific enough but unfortunately it's all I have at the moment. It should be noted that this bulider is not the original builder of the engine and some parts, including the the push rods, were reused under the assumption that the orginal builder knew what he was doing (obviously not an accurate assumption as it turns out). I asked about the cam and he said that it was fine, no damage but couldn't provide any other specific information. The engine at idle is lopey (not full race lopey! lol). My son who was at the shop took a picture of the rocker assembly and said he would email it to me... I will post when I receive it.
