Picked up my flywheel from the machine shop today. I asked the machinist about shimming the flywheel, he said it wasnt neccessary because they take less then .010 off the surface... Is this true or should i be looking for shims myself, and a new machinist?

Some flywheels have a minimum thickness spec, just like OHC cylinder heads. So yes, flywheels can be re-surfaced too much, if all they removed was .010" then you have plenty of material left. Flywheel shims are avalible in thicknesses of .025" and .050".

 

Sorry to use this thread, but do you know what is the stock thickness for an LT1 flywheel? I have an aluminum one that has been resurfaced and I might need to do it once again. I'd like to know if I can reuse it.
Thanks.
