I thought it was ridiculous yesterday when I pushed my car down the road after it spun a bearing. 
346 is now dead
346 is now dead Well I finally pulled my head off the car to see what was making all the noise and here is what I found 
The head is pretty beat up and the piston is all hacked up looks to me like possibly rod bolt failure as the valvetrain looks ok up to no broken springs or rocker arms so what else would that leave? oh yeah I also had parts of the piston ring in the damn intake kind of a sad day, but the upside I get a new engine!!

Thats the normal broken piston ringland on #7 that happens to alot of people. A chunk of the ringland breaks off and bounces around destroying everything. Same thing happened to me...

Ya mines blown up too. And it only had h/c. Beginning to wonder why I went away from the sbc's. Seems like these 346's are a bunch of pussies! you could throw alot at a 350 4-bolt main and it would laugh right back. Seems as if you fart at a ls1 it will choke and die...
sorry just a little disgusted

my engine didn't go, but my a4 gave out the other day and is dipping into my Catastrophic Engine Failure reserves.
if my engine or rear end give out next, my ss will be collecting dust for a few months.
gotta give gm credit for producing cars that put out enough power to break themselves
