Hi again! Got my 289 freshly built and Im doing the firs kms al tow Rpms.. but I recently felt a weird noise in the top end of it. It kind of fade side to side.. or at least I can't find there exact place of that noise. It only sounds when is hot and doesn't follow a real pattern..
Thanks!!

Find a friend to run the car, get a mechanic stethoscope, and locate the sound. That will narrow what it could be.

If you can video its occurrence and post it, it would help a lot.
