About friggin' time! That book has been delayed since before the 2004 V8
meet!
Did they mention what the delay was about? I just checked, I first ordered
that book June 14, 2004.
Sounds like GM's investment casting process was superior even if more
costly.

Subject: Warning: coolant temp. and cracking in Rover blocks
> All,

> 25% of the big-bore blocks will develop a crack. But it gets worse:
> For a few models, Rover installed a higher temp. thermometer in the

> rate goes over 50%. So the book recommends that all Rover engines run
