That is what my brother was thinking. He was thinking valve train related but we will see. He is going to come over and see if he can figure out if it is the top half or bottom half or even if it is the engine. Doesn't matter if I am in gear, park, or neutral. You can hear it. Cam isn't very big but does have a lot of lift. over 600 on both intake and exhaust but is mild as a performance cam goes. 216 228 118 lob separation. Has the CHE package and appropriate valve springs from when GPI installed it and the GM performance parts caddy lifters.
I have had a motor with a rod knock before and it doesn't sound the same from what I remember. Rod knock sounded lounder and like a hammer hitting. This is more like a box of rocks moving in the engine or clunking. It isn't high pitched either. When my brother comes over I will record it and post it if I can. Want to start it as little as possible until I know what it is but it has oil, pressure and good oil. It is full with the driven 5w 30 ls motor oil GPI filled it with still and isn't low or dark. Oil looks good.
