My new 347 has a lot of top end noise its not a lifter clicking or any thing like that.It sounds more like chatter coming from all the lifters or rockers or it my even be described as alot of motor noise has any one run in to this before.Does a roller motor make more noise like this?
Roller rockers are very noisy, this sounds like what u described, nothing to worry about. I have a set of trick flow roller rockers and they have alot of chatter!
