Went to Dragway 42 last night, got some new bests. First and best run out of the box, 12.40 @ 108.18 with a 1.7689 60'. I did hear after each of the 2 runs I made heard the valvetrain clicking, and then would go away after idling and cooling off. Any ideas why? It did have some KR during first run, but fell off. Second run, I lowered the Boost down 1 turn on my RJC which brought it to 20 psi from the 21-22 on the first run and only had .7kr. However coasting/driving to get the timeslip the KR on the SM2.1 was jumping around a bit, then stopped. I did switch to regular 10w30 from the Rotella T 15w40 since I have ZDDP now. Still drove home fine without any issues.
