I searched and found one that said the main saddles had cracked. That's severe. All the others were due to catastrophic failures or amatuer hour at the head swap shop. Water doesn't compress at the bottom of a head bolt hole and when you tighten the head bolts it blows out the aluminum and breaks/cracks the block. I've even done that one myself long ago.God, did I honestly admit that in a public forum?

There were a few iron block cracks as well. I didn't find one "I was out four wheeling in my crew cab 4x4 and my newly swapped LS1 block cracked in half" or "I was running 10LBS of boost on my LS1 at the track and the block just cracked in half".

FWIW or for those that might want to know, the L92 block is aluminum according to Scoggin Dickey.
I found one post of a guy that cracked his aluminum block in the oil galley when he did a wheel stand, lost control of the car when it came down and destroyed the entire front of the car. I think it was TTP's Camaro.

Ok this wasnt meant to start a thread war...I didnt say aluminum blocks will just crack. The key words that you are missing from every single one of my posts is that "UNDER ENOUGH PRESSURE,TEMPS,and or LOAD" and aluminum block "WILL CRACK B4 an IRON BLOCK WILL" Not aluminum is crap cause it will crackimmediatly, not Id go iron cause aluminum is going to crack when you drive it. I didnt even say anything about horsepower or torque. ALL I SAID WAS THAT THE METAL IS MORE LIKELY TO CRACK B4 B4 B4 damnit B4 and Iron block will thats all. I didnt say Iron was invincible or that aluminum is made of copper and cracks when you start driving. Please don't put more to my posts than what im actually saying. I love you guys for the same reasons that all of us do. INFO...If my info is not worth being posted then i wont post. But if someone asks why they dont see alot of people doing something and only one answer is given I try to give a little more to think about incase they decide to put 1500HP in a truck that weighs as much as mine does. I was new once too and I had to learn this stuff just like everyone else
Please dont try to be a smart ass.Originally Posted by Quik
6.125 im sorry i missed the 1 key.
In case you have no idea about that since you like to make people look stupid ill make you look just as dumb. Even a moron couldve figured out that i mean 6.125 rod length.
LS1 6.125 rods - LS1TECH
wtb 6.125 rods for ls1 - LS1TECH
Affordable 6.125 rods? - LS1TECH
Do I need to post more links for you or can you handle the search button??
And quote me where I back pedaled please!!?
Here's my original post to this thread "
LS1/LS2/LS6 = bad idea on 5000lb monsters...if you put the power to it that is!! You have a much higher chance of warping or cracking the block with that kind of load" find my back pedal
And for the record, if youre going to make fun of someone, at least use the proper spelling of words...Mr. I know more "then" you.

mitch cobb racing: ya, allen played with it for a while, HUGE difference
What I think is funny is you can really see how if one persons comments dont agree with everyone elses, they get attacked. right or wrong I think yall should have been more mature in how yall handled it. No reason to be hostile, thats what the dodge guys do when they loose. We arent dodge guys, we are Chevy guys, smart, loyal, knowledgeable and we are suposed to stick together. And In my opinion If I had a choice between A Lq4, LQ9, Ls1, LS6, LS7, LR4. Id choose the LS7 or the LS6 if money wasnt a thang. Only because in my experience an iron block heat cycles different than a aluminium block. And if the heads are aluminium, they heat and cool at the same ratio. IMO dont hate, listen and learn. I may be wrong.
Face it Quik, You lostThats why you resort to the little snyd remarks that youre using now. thanks for playing the game. Oh btw if you learn how to read, you'll know that half the claims you say in this thread are BS
I never once back pedaled which you still failed to prove.
I proved everything I said with links when needed.
And If its still rocket science to you on how Aluminum just plain old isn't stronger than Iron. Then you have alot more issues than just being dumb
When you have some facts to prove ANYTHING that you said today in this thread is fact and not your weak @$$ opinion then Ill bow down. Until then STFU unless you have somethin constructive to say.
You tried and tried and tried to make me look dumb. Then you gave up, then your moderator friends came online to say something then you jump back in again. Then they realize that what i was saying holds truth and now you resort to being the small guy again. Be a leader not a follower.
