its best to give it a few hundred miles or so for everything to completly seat before hammering it.

everyone has a different look at how to do it, but we on initial fire up idle it around 3k or so till it warms up, then swap oil, then go out an gradually over a few hundred keep increasing the rpms.

your noise could be anything, odd that it comes and goes, honestly could be a number of things without hearing it personally

Next time run cross the sound I will post it online.

Did you like the before or after part. Why does it smell like dead fish when you walk in the room?

Just from personal experience I would not hammer on a new engine to much. I built a 302 Ford years ago and beat the hell out of it right away and tore the cam up.

since you have allready 400 hard miles, go ahead change the oil and the filter, make sure its warm when you do this, and let it drain completly, then replace with whatever oil you plan to run.

normally you can take it in steps, but most likely you have everything pretty much broke in, the thing to kinda stay away from is redline pulls for the first 500-1000 miles, take it to the upper rpms, jsut not at full throttle or a constant top end run, after say another 500 swap the oil again, at that point if you want you can grab a sample and get a sample kit from napa or catapillar and have the oil checked to see if there is any premature bearing piston or ring wear
