I never looked, but do our engines have a damped crank pulley/harmonic balancer from the factory?
If so, wouldn't we want a replacement to also be damped, maybe even better than the factory one (a la all of the ones offered for the LSx engine platforms, like the Fluidampr I had on my Z28), to kill the 'crank harmonics'?
Even if the factory one is not damped, would we benefit at all in (main bearing, crank/rod journals/wrist pins/etc.) reliability/longevity with a damped performance oriented crank pulley (like an ATI), especially when using raised rev limits, or is our engine just so perfectly balanced right from the factory, despite the 'stroker' geometry, that NONE of this even matters?
