I’m building a 383 LT1 motor using a solid roller cam. I went to set the valve lash and noticed as I rolled it over there is spot where it becomes extremely difficult to turn over and it makes a small “clink” noise when it hits that point. Before putting the cam in everything rotated fine with no extra drag at all. If I push hard enough I can get it to move past that point and it will roll over fine until it hits that point again. I’ve gone over everything and can’t find anyplace where parts are making contact. When listening to the noise, it sounds like it’s coming from the springs. I’m thinking the noise is from the coils of the inner and outer springs hitting each other. Does that sound possible? Is this a common thing?
Sorry for what little info I have at the moment, but any input would be greatly appreciated. I can’t seem to get my head around this one, and just need some ideas to help get me started.
