Tell that to the guys that go to start their engines after a rain storm and they toss a rod out the side of the block. Cast Iron engine woooood just lock up, cheap aluminum blocks come apart.

That has nothing to do with the integrity of a block they sucked in water that SNAPPED a steel rod and sent it through the side of the block. if has enough power to break a steel rod 1" thick it has enough to break an iron block... Btw should I tell my friend that just had a leaky injector on his 5.0 cause a hydrolock and cause him to leave half of cylinders 3 and 4 on the driveway that it cant happen to an iron block? Bottom line is you shouldnt be hydrolocking engines they werent made to do that and run ya know lmao.

I seen COUTLESS cast iron engines with bad head gaskets that hydroed as you tried to start them....NOT ONE EVER ruined the block.
FACE it aluminum is junk! thats why they use it to make soda cans....it throw away garbage.
Don't bs me i've bean doing this a VERY LONG time.

BS you don't even know what i'm talkin about.......You'r telling me that water in a cylinder that leaked in while the engine was shut off AND NOT running should be able to break the block as the starter turns the engine over????????

But ya we get it you just dont like aluminum its ok, btw the reason they use al in soda cans is that it doesnt rust and is lighter than steel... Theres no point in arguing anymore with you as you are the only person who seems to have a problem with aluminum blocks in this thread. One other thing I dont care how long you've been doing this, it's kinda like riding a bike just because you may have been doing it all of your life doesnt mean your Lance Armstrong. Get my drift?

Aluminum blocks are weak, look through the posts on this site. I'll bet there are 100's of posts about blocks breaking at start up. Thats just unacceptable in a production engine IMO. At least they should have not used a reduction starter and save the block from damage. NOWAY a starter should be able to develope enough force to ruin the block. I think gm engineering is lacking in this engine's application and supporting systems. Same with the intake design and windshield, If rain water is going to allowed to flow freely over the engine at least it should be water tight that water can't enter the intake. Maybe a cheap 10 dollar plastic cover? Anything to save the poor soda can engine.
They even sound like a soda machine with all the clicking and knocking and ticking. Sometimes I expect a tilt light to flash on or a couple quarter's to pop out the dash.

WOW... U do realize that none of what you said up there makes any reference to the strength of an aluminum engine right? The sewing machine noise is common on all commonly based lsx and lqx engines so I'd say its more of an aluminum head trait more than a block trait. And once again if cranking a motor over has enough power to bust a rod it certainly can send that piece of the rod through a block iron or not... OP sorry for jacking your thread I'm done answering to this guy, a lot of us have explained why the motor is great and proven he's just one who happens to disagree and skews the information.

LMFAO at this but at the same time I love my ls1 soda/sowing machine.
Theres no doubt these engines are VERY reliable I am on my 3rd ls1 camaro and never once (knock on wood) have I been left stranded anywhere.
Now although I believe that this aluminum block can hold alot of power I wouldnt expect it to hold more than an iron block. Ill have to agree with 02form because aluminum just isnt as strong and probly is more fussy than an iron block but ill also say that aluminum block isnt as bad as how 02 form is making it sound. Theres my unbias .02

Cast iron blocks are just about bullet proof, Aluminum blocks are crap. They are high tech, fussy and full of problems. I've seen cast iron block ran WITHOUT coolant that melted the cam bearings into the mains AND after freshing up up they still run fine. Aluminum blocks are touchy, just ask gm how many they toss out in a production run.

After building, yes actually building 302's. Including, boring, honing, decking & milling.
The 302 is a good powerplant, don't get me wrong. It's plenty capable of 400 RWHP Reliably, however anymore than that and it's a timebomb. They split from the lifter valley straight down to the pan. The rods are also an incredible weak spot, being iron rods they warp easily under detonation. After enough detonation the 302 pistons pit and crater I can send you a dumptruck full of detonated pistons even out of low mileage blocks.
The ls1 however is 100% more efficient at dissipating heat and expanding/shrinking. A H/C/I LS1 can put down near 470 RWHP and be incredibly reliable.
The only known problem is the upper ring lan inbetween 3k-3500 rpm's under light load floats and burns oil. And the short skirt pistons wobble slightly when cold, which is the knock. But my ls1's only got 113k beaten on miles and still leakdown & normal compression testing 97% of highest!
Have you also seen the crank walk on the thrust bearing, these little ******* move around alot.

Idk why you're on an LS (aluminum engine) forum when all I ever see is you bashing them. You say you've been doing this a while and that's obvious too, you cant teach an old dog new tricks right? Well here's a new trick! Lightweight, perfectly reliable, fuel mileage and performance enhancing ALUMINUM v8 engine. If you don't like the new stuff go play with a small block!
Seriously If you don't like it then go watch Bambi.
If you can't say anything nice, then don't say anything at all.

ok but lets be real here. we can play the shoulda woulda coulda game all day long with gm, mopar, ford, datsun, honda, toyota, etc....you get my drift. I feel very confident that many improvements have been made since the LS1's creation
