Default will a built block change knock signature?

Searched around and didnt see what i was looking. So, after a built block, is there gonna be a change in knock signature caused by the new internals and noisier engine? The stock knock sensor is still reliable right?

It's my understanding that it does, but by how much I dunno. PM Clark Turner or mick_the-ginge. They'll be able to confirm one way or another.

I've got a motor built with CP pistons and there is more piston slap (aka noisier). The maker the pistons has quite a bit to do with the noise level. But yes, when I went to a built motor it sounded much much different.

More than likely you will tune the knock threshold while you are tuning for the new built motor.

ok, just wanna make sure the knock sensor will still serve its purpose and that theres no decrease or increase in threshold and im fine with it.
Do you guys know if a built block will take timing advance better? Ie less susceptible to knock, not the damage it cause.
