Didnt see this thread go this far.
With reguards to blocks cracking, I was the person who conducted the survey on the american board so I am familiar with the rev 1/2 block cracking, but you must also remember that the americans only recieved the rev 1/2 blocks and rev 3 are rare over there and the states is a big place.
It does appear that any block can crack, even those with sleeves, I was making the points with regaurds to going 87mm bore, I seriously think its a problem which is more to do with high powered cars with very tight tuning where its maybe been taken a little further than most of us would safely stay.
There are indeed, a hell of alot of 400-500whp 3sgte engines around, if your block is going to crack then its probably going to happen no matter what, its luck of the draw, my last engine was a thin walled rev 3 and was fine.
Its a very odd subject with no true solid facts or figures I have to agree.
You might spin a rod bearing or detonate long before the block would crack.
Luck of the draw high powered tuning is.
That im sure we can all agree on
