Re: What is reasonable charge for engine work? 59A
Actually the annealing he is refering to is associated with the cast iron. It is more a form of metal fatigue that is related to some measure of annealing with temperature cycling but how much the affect is depends on the amount of cycles endured over time. Steel hardware would not be affected by this but can be affected by other forms of metal fatigue.
There is also some contention about the blocks being closer to cast steel than ductile cast iron or nodular cast iron but there is a fine line there about carbon content and I still haven't heard of anyone other than Joe Abbin doing any metallurgy testing there to confirm or deny the results. The fact of the matter is that the damn things do crack no matter what the make up is.
