And is there any problems just cruising an aluminum block on the street?




and just because a handfull of people did it does not mean it is reliable.





Why isn't it reliable? Please, do tell? CHIP



my point was about the pressed in sleeves possably leaking if nothing else over time.




The old aluminum blocks had wet sleeves with O-rings that sometimes leaked. Not anymore, they now use dry sleeves and have done so for many years. So no worries about leaking water. CHIP
