Inside the LSX 454

[MrGrayfox87]

What mods recommend for a 231 v6 buick?

[richieb74]

i build these for a living, there solid engines. and chvyboi this is in the ls engine family

[need2speed94]

I'm a die hard Chevy guy, but this motor transplanted in a Shelby Cobra or a Cobra kit car would be one hell of a machine! Hope to see that one day... or better, create that one day!

[nickdec19]

Before that happened with the wheels slipping on the dyno it was like 700hp

[nickdec19]

My friend has an ls1 camaro that is procharged making 18lbs of boost and when they dynoed it the head lifted off the block lol

[syfe45]

Is the Ls7better the Lsx Sombody tell me

[Curveball]

@syfe45

No, the LSX is a better motor. A lot better if you plan to force feed it.

[pissedcow]

my lsx 454 block had thin cylinder walls. DANGER! my lsx454 has a defective thin casting.

[carwhore88]

he's like a grown up version of the kid that was in hancock

[prostreetbuyer]

DEAR GM PERFORMANCE PARTS-WILL YOU HELP?

MY LSX 454 BLEW UP

Recently I was influenced to purchase a Chevrolet LSX-454 engine for my 2010 camaro based on information in print and in person from Dr. Jamie Meyer, the Product Integration Manager for GM Performance Parts. THE BLOCK HAD A CATASTROPHIC FAILURE.

[MrMrsmotley]

@prostreetbuyer I purchased the lq9 6.0 better block. you can turn it into 421 stroker. jegs sells the kit for around 2300 bucks.

[syfe45]

@prostreetbuyer how much power did you put into it before tht happened??

[MrMrsmotley]

what good is the flow of the heads if you dont give it more coolant flow. my shop partner has one and it should be faster than high 9's on the track. the heads bring in more air than they exhaust he changed the cam 635/635 he ran low nines. i think he should change the pistons ang get a better carb.

[MrMrsmotley]

I'd rather have the lq9 6.0 out of the H2 hummer with a lunati 581/588 roller cam ,springs and a procharger.

[vazqua432]

MY 454 LSX IS  IN MAKING ALREADY

[papaown]

@vazqua432

WHY ARE YOU USING CAPITAL LETTERS

[vazqua432]

MY 454 LSX IS MAKING ALREADY

[nogangstalean]

can u super charge this engine and how?

[NSX86R]

What's it's weight? Fully built.

[704Ch3vyBoi]

best engine GM came out with since ls series family

[simracr94]

@704Ch3vyBoi eh, disagreable.

[704Ch3vyBoi]

@simracr94 so what would u suggest?

[simracr94]

@704Ch3vyBoi 427 tri power. Imagine one of those things with all the new technology. 750-800 horsepower probably isn't out of the question

[IRONSEAN7]

TURBO v8s =  no more Fast N furious movies!!!! :)

[MEADOWSracing78]

i jus cummed in my pants

[marek0086]

Are they retards?!.... Who the F#@k would want to use a "wet" manifold with port-EFI?!

[levisnteeshirt]

those tiny main cap studs can't be good 

[c3h9e4v7y]

@levisnteeshirt there not studs there bolts!! the studs are for the windage tray.. IDIOT!

[levisnteeshirt]

@c3h9e4v7y i've saw one with studs in it ,, dumbass ,, and ,,, they're too damn little

[c3h9e4v7y]

@levisnteeshirt fuck your an idiot

[levisnteeshirt]

@c3h9e4v7y yeah ,,, you know i'm right ,,, they look like a light weight ford product ,, what the hell has happened to GM ?

[c3h9e4v7y]

@levisnteeshirt man it doesnt have studs are you fucking blind or just stupid, its got 6 bolt mains , thats something you find on a top fuel dragster, its not light weight

[levisnteeshirt]

@c3h9e4v7y i saw one beside my block at the shop ,, and it had studs ,, maybe someone added them ,,, they look small ,,, the cross bolted mains your talking about are most likely what keeps it from exploding ,,, the tiny fastener for the rockers doesn't impress me either ,,

[levisnteeshirt]

@c3h9e4v7y they're light weight ,,, it looks like its straight from tawain

[levisnteeshirt]

@c3h9e4v7y  they're built light weight ,,, what about the LSX that the bottom of the block failed ,,, Now GM won't help him out with a new block ??? drop in the bucket for them ,, big deal for somebody that just laid down the cash for a new motor ,, to find out the block is cast as thin as tin foil ,, if GM feels so strong about their motor they should take care of it and stand behind it ,,,,,, its no wonder we had to bail them out

[BLACKLACDTS]

@levisnteeshirt the lsx block is capable of holding 2000hp.

[levisnteeshirt]

@BLACKLACDTS they could have made a crate motor out of a 9.300 gen 1 bowtie block , 18 degree heads ,, and had a real animal ,, 447 or so ci ,,,

[BLACKLACDTS]

@levisnteeshirt yea but that would of been a lil to radical for them. thats what the aftermarket companys are doin.

[levisnteeshirt]

@BLACKLACDTS why rod of heritage if its that good , ??? they could have made a 500 ci motor as easy as a 454 ,, they could call it a LS whatever , instead of LS7 ,,,, they're on the cheap

[BLACKLACDTS]

@levisnteeshirt i cant disagree with that. they had to make it the 454ci that was the goal. i like the motor but i think for the price i will build my own version. i will build my aluminum ls2 to about 408ci with afr heads,fast lsrt intake,comp cam and make just as much power if not more. you can re sleeve the ls2 to accept 454 cubic inches. chevy magizine just did it.lol

[levisnteeshirt]

@levisnteeshirt *rob the heritage *

[syfe45]

@levisnteeshirt Is the Ls7better the Lsx Sombody tell me

[calgrizz52]

@syfe45 the ls7 is a 7.0 L engine while the lsx 454 is 7.4 L. More displacement= more power. The lsx is just a bigger, tougher, and more powerful engine than the LS7. Hands down. And the LSX is an engine that can hold up to 2500 HP. The LSX is a pure racing engine that is meant to be upgraded and used for racing. Ohhh and the LSX had more bolts for the cylinder heads so you can put more boost in the engine without the heads coming off. lol

[syfe45]

@calgrizz52 thank you!!

[ThatMiserableCat]

@calgrizz52 The LSX 454 looks like it would be the logical replacement for the 572. It being smaller and lighter, and if able to handle serious horsepower upgrades, I think they may have a winner...

This has me thinking about dropping one of these with Fuel Injection into a '96 Corvette as a daily driver!

(hope it runs on pump gas)

[RYANSCHLESINGER]

@c3h9e4v7y actually a stud is what i am

[50908]

The GMPP LSX block comes from the factory with a 3.860" bore, and can be bored to a max of 4.250!

[cjonesufc]

454 winding to over 7000 rpm... Damn... That block is rated to handle 40 lbs of boost and/or 2500 hp. At the power rating this thing is making that engine is damn near indestructible. I want one.

[gearhead632]

ok but they look like hypers



[gearhead632]

how nice motor but why hypereutectic pistons there garbage

[ssn8r]

@gearhead632 it is forged pistons not hypers

[marek0086]

@ssn8r~ u can have forged hypereutectic u know?

[dcanaday426]

only 11 grand!

[Red97Avenger]

i wanna stick that in a 2g rx7 : D

[thevettedude66]

tt one of these and drop it in a z06 thats they way thye should come stock

[shaggyC5Z06]

@thevettedude66 no please leave the z06 alone. Z06s are balanced track machines. i hope chevy just puts such TT monsters in hopped up camaros. no point in putting so much power that you cannot put it to the ground. But camaros are optimum market for that. :)

[OriginalSamsquatch]

So when they go to 4.25 bore do they use machined copper rings like the 454 smallblocks or do they still seal fine with MLS gaskets?

[duramax3388]

i dont have anything to put one in but i still want on lol

[drizzetsrevenge]

Doctor? How do I get my doctrine in automotive?

[artwigginsjr]

@drizzetsrevenge Im just reading this and saw your question.... but to get a Doctorate in automotive, well one way is to get a PHD in engineering. Im pretty sure thats what he has. sounds cool though dont it?

[jfl187]

i went to the shop to pick up my little Lt1 and there was a freash LSX block sitting there. awsome piece of work

[superduc99]

Junk!

[cienporcientoculopri]

will it fit in my 2 dr gmc truck??

[xxxxdarksidexxxx]

100mm turbo np!

6 seconds capable

injector bungs, fucking awesome!

[LSXgoat]

best investment you could make

[Camaros5678]

they magnacharged a LSX on 101 octane 15.5 boost and made 950hp!

[babygirl942000]

what is the cost of the LSX 454?

[1969CamaroSS396RS]

Bare Block is around $2000

Turn Key is around $15000 from pace performance.

[drizzetsrevenge]

but well worth every penny!

[duramax3388]

i have seen them for sale for 9xxx.xx not a bad price for the whole deal

[SolidSnacks92]

thats nice i want one

[drizzetsrevenge]

save up your money

[babygirl942000]

How much is it?

[cantbuytime]

way too much money for a mesely 620 hp.. you could build a 454 or LS1 (BOTH W/CARBS) for the same price and get more then that in horse power. either way it just looks cool. why pay all that when you still have to spend more time and money to get the horsepower it should already produce ????

i think old men with money and young people who cant build engines buy crate motors....lol real hotrodders build their own engines ..... and dont pay people to build their engines or cars...

[VayLoc310]

I agree, people who don't know how to build a motor will go buy a crate motor, I get a lot of negativity cuz l'm the only person who will build a 305 or 350 to the hilt!, most people tell me I'm waisting my time building a 305, I say no I'm not, cuz even tho it has a small bore, .194in smaller than a 4.00, you can still bore it up to .060 over and get almost 500hp from that 305 block, it's all about realizing the potential in what you have and exposing it, which is what most are too lazy to do

[cantbuytime]

305 motors are just small bore 350's... well people that say that 305 or 350 are a waste of time dont know enough about engines to be talking.. i have seen a 636HP 305 in a chevy 1/2ton that ran 12.90's in a 1/4..

anything is possible.. check out my profile.. just added vid of my big block

[VayLoc310]

You know where most of that money is?, the cost of the LSX block!, mutha is expensive

[nickelisio]

I believe the block can take over 1000hp. As it sits. I think that was the original point of the lsx, the trick ass engine block. Everything else is simply extra lol. :-)

[chickensedan]

They said that they put twin turbos on it and got 2500 hp so that's as much as they've tested.

[Rusty91o]

Mmm 454...

[getalife04]

I just ordered one of these for my project car which is a 1985 Z28 Camaro had a blown motor and got it for cheap. I am going to strip it out and beef that bad boy up and see what it can do. I can't wait to get it in.

[musicequalslife008]

i wanna put one im my ls1 camaro.

the're beasts!!

i think its crazy it can revs over 7 grand

[ThunderAppeal]

I wonder if I dialed back the HP would I be able to get 30mpg....muahahahaha!!

[dajudge1969]

you guys are retards, anyway that engine is nasty to the bone, once I get my car set up the right way i want to chuck one in my GTO and work those heads over a bit and do a ported intake on the sob, that thing should crank a good 800hp

[IndyFan53]

That would be sweeeet! If it's a 1970 or later, bore it out an extra cubic inch to 455 c.i. like the super duties from back in the day! Traditional GM heritage!

[Mr232172]

I want one for my 86 Tercel!!

[iiiTEDiii]

Will it fit in my Achieva?
