So, I was at the track the other night and saw a 5.0 block in the bed of a truck where every cylinder wall was destroyed. The mains and crank were perfect, but the cylinder walls all had cracks in them.
Upon closer inspection, I noted that that iron sleeve for every cylinder was VERY thin (I was told it is only .060 thick), then of course you have the aluminum right behind it. So at only .060 thick, this would make any over boring for clean up an issue I would think.
But more significantly, I was told that the cylinder walls all failed at 16 psi of boost. Which brings me to my question---what kind of boost are the big boys currently running--and has this failure happened to other cars out there? It seems to me the 3V block is much stronger, but I am far from any kind of 5.0 expert--just commenting on what I saw.
I didn't have my camera, otherwise I would be posting some pictures. The carnage was pretty complete.
