With the new items installed new noises are being picked by me as the ambient noises go down.
Around the 2000 rpm area and up to the 2600 ish area when holding the pedal steady i get a chattering sound noise. Not a deep hard knock by any means. seems to be present only when under load when driving and not revving stationary. This sound like rod issues? Engine only has 1100 miles on it now.

Ball-on-the-needle timing is a good start. Seat of the pants is a better finish.
