I guess I hadn't considered the aluminum and iron blocks would be different.
It's my understanding that 6061 T-6, 7075 T-6 or 356 T-6 aluminum alloys have
essentially the same strength of mild steel, not sure how it compares to cast
iron used in engine blocks. However this discussion has made me run to some of
my reference books, I found that cast iron strengths are all across the board,
some are much less than aluminum and some are much higher. I guess I have
enough information to be dangerous (and inaccurate) so pick and choose what ya
believe.
