Once again, thks. Jack for informative & prompt reply. I think you have cleared up most,or some of the confusion in my mind re. this subject. Every time in the past discussing this topic the 'Aussie' block comes up. But,I remember you or perhaps Mark,last time ending up with the fact that these specially cast, race-blocks were as hard to find as the proverbial. -Is this the block u are refering to above? I would think not,since everyone has said the likleyhood of finding one of these, specially cast;'racer-special'blks. sounds like zip. So,are u then perhaps refering to the many Aussie blks.that populate South Africa / Europe originating out of the many Aussie Falcons / Fairlanes etc? I had always heard in Europe, long ago that De Tomaso was suppied from these sources when the USA 351C's were fazed- out in the states in the early 70's.We were told that the aussies were recasting these blks.using more metal in various places, hence were heavier and stronger, & also to be used in numerous truck applications. So one might then presume that all Pantera's after the 1974 USA 'shut-down' were supplied from this source? Or do u think these only went to non-USA countries?
This would account for the fact that NO one I have spoken to here in SA have ever experienced or heard of any 'thin-walled' problems with over-boring the blks.here. Even in severe high horsepower usage. Interesting.
And now for the million dollar question Jack? How do I tell which my block is? -I will 'surf' the aussie electronic-ether and try and find out from their side. Many thks again Jack for your appreciated input. Any one else? Regards tai.
