I'm thinking everybody is wating there time even posting here. This guy is a on a one way mind track. He has not answered any important questions
except quoting stupid crap. He abviously has limited knowledge of engines ect. There is a ton of stuff that could of damaged that block. He's going after the damaged caused and not the reason why it got damaged.

The LSX engine that prostreetbuyer used had defects in it. Alot of ppl on this thread are in denial ,they cant accept that some of the LSX stuff have defects in it. . I seen cylinder walls crack like this on NA sbc with bad core shift.

ANOTHER GEEK INTERNET EXPERT. you're getting your silly numbers from a jegs catolog? my numbers come from the real source "GM performance parts"
http://www.gmperformanceparts.com/_r...09_Catalog.pdf
page 200, 3/4 down: Maximum 4.250" bore at .200" minimum wall thickness
and you got the nerve to say its out of context?
i'm done informing you mongoloids of facts. you just want to disagree like a lynch mob. this is my last post here. goodbye and good riddance.

Here, I'll quote it again, this time with bold in the important areas just for you.
I dont know where you got that data, but it is a little different, and a little out of context from the data I've seen..
Maximum 4.200" bore at .200" minimum wall thickness (naturally aspirated applications)
source: http://www.jegs.com/i/GM%20Performan...0002/-1?CT=999
Maximum 4.200" bore at .200" minimum wall thickness (naturally aspirated applications)
source: http://www.jegs.com/i/GM%20Performan...0002/-1?CT=999
And yes, you DID take it out of context buddy. You forgot the part where it says that max is for "naturally aspirated applications". You can't leave that part out or you are taking it out of context.
See page 200 about 3/4 down for the WHOLE quote:
• Maximum 4.250" bore at .200" minimum wall thickness
(naturally aspirated applications)

Maybe if you pulled your head out of the sand you would realize that this isn't a lynch mob, it's a large gathering of people with specialized knowledge involving anything LSX with boost. A couple of top level racers and the guys building their record setting engines have posted. You have ignored them and skirted every question or request that has been presented to you. I'm happy your engine blew up. Maybe some people will learn from your mistake and at the same time we will have 1 less 5th gen owner driving around with 1000whp thanks to no brains and a blank check.

We're not a lynch mob. In fact, I'm bummed out that you had engine problems, I've been there and it sucks. But the tone of your threads is not constructive, trust me, I've been on boards forever, and I started this board... What do you hope to accomplish with these threads.
What you should do is find another shop to handle an FI setup for you. Someone like a Speed Inc though I'm sure your threads make just about any shop nervous, because you don't know what you are talking about (I've been there too) and are unwilling to listen.
By the way you should tear the motor down and figure what happened. Had you done that first maybe GM would have been more receptive.

Dang check out this thread in Oz

Is that pic of your block? That is insane how thin it is on the back cylinder, then fat up front, those LSX blocks are junk. Maybe building a boosted 454 wasnt the best idea but who the hell would expect that!!! Who would think a boosted stock LQ4 block out of a junkyard would be more durable than putting the screws to a 454 block. Maybe not many boosted ones, but I could see alot of people thinking they could throw a 200 or 300 shot on these and blowing them the same way.

The easy way to crack a block
My machinist warned me that the #1 easiest way to crack a LS cylinder block is to leave oil or antifreeze in a head bolt hole and bolt down the head. Hydraulics do the rest......
