I agree. Was just talking to another guy that's in the industry and he believes all the cam manufactures use the same material for their cores, they are just ground differently. I think its a quality of material issue. So I am going to try not to dwell on it, Ive always used comp. My dad just put in a roller for his 383 and so far so good. I am little nervous on the lifters, but then again, what can you do?
You can also google FiTech, Edelbrock Proflo, Holley Sniper and get a ton of hits on bad parts/systems. So I think that is just the way it is now with so much access to information.
