Super tuning car runs good shooting for great

Yeah, I think I heard it that time.
But I thought I heard a couple of shots of detonation too.
So,take it up to about 1500/1800 and just gently roll in and out of it. Loading and unloading the rod. When you roll out, roll slowly.
I don't want to say it sounds like a rod bearing just starting , but it sorta does, sorta. See if you can get the stethoscope on the oilpan,above the liquid line;then have a helper,do the above test.This requires gentleness, at power on/power off transition, and only varying the rpm maybe 50 rpm or so. You are looking for the split second where the thrust transitions from pushing up on the piston to pulling down on it.That's where you'll hear a rod bearing this early in the game. Or a wrist pin.
The rod is a deep tone thud or clonk (rhymes with bonk).Kindof; clonka...clonka...clonka ...And the rod kindof echoes in the pan.
But the wp is a much quieter sorta double tap,having a very short attack/decay; kindof; tapatapatapatapa.
I hope it's neither!
But if I had to choose, it would be the wp; I think,lol.....
