Do you really think that any more than 1/10th of a % care about your irritation level with a thread you find irritating...???

I happen to be in the above mentioned 1/10th of a % minority performing a major engine swap...I'm trying to gain a knowledge that may help me avoid similar situations in the future...

IT'S REAL SIMPLE.... If You DON'T want to read it... don't click on the thread... Is that so hard... (edit: follow on comment deleted in the interest of being nice........r)

I'm also curious about by whom the book was written...

Chevrolet announced last week to ALL their racing teams that ALL engine failures would now be the responsibility Of Chevrolet Motor Division. They further stated that failures due to such things as over boosting, bad gas, over reving, over heating, valve to piston slap, detonations, misassembly, bad tuning, oil starvation, valve spring breakage, water ingestation, spark plug failures, ignition failures, etc.etc. would now be the SOLE responsibility of Chevrolet Motor Division. In other words, you can pretty well do just whatever the *uck you want and THEY are responsible for it.

Congratulations, THIS seems to be the answer to your problem. Baby Wipes are currently on sale at local pharmacy.

What compression are you going to build your new motor with? I doubt you're going to make the same mistake twice.

my destroyed lsx454 crate motor was 11 to 1 on c-16 with a vortech intercooler.

and how much boost did it say they run in race boost compression engines? does it say in there that you should take an engine that is spec'd and designed to be maxed out running N/A and throw a s/c on it just because someone else ran high cr with boost or because "some guy" said it was "ok".


Your whole subversive argument is ignorant.


as for the LSX454, what you should have done (if you had any clue what you were doing), was to buy an LSX bare block and build it from the ground up instead of trying to double the power of a nearly-already maxed out NA crate motor. this same scenario has played out with the LS7 and people throwing tons of boost at it and grenading their engines. but, if they build a 427 LSX or RHS block they never have a problem.

as for the block itself, its very possible that there was a problem with the metallurgy, but with your personal actions regarding the issue, I don't blame GM for not wanting to touch this issue with a 10 foot pole.

Maybe you should be talking to the guy who wrote the book:

Joseph Potak is a professional LS-series engine specialist and technician. He has worked for Texas Speed and Performance since 2002, and caters directly to the performance needs of owners of LSX equipped vehicles. In his free time, Joseph volunteers as a Forum Director within the LS1Tech Community.


LMAO! It doesnt take much to be an author and tech is a sham of a site. Anytime you have mods an admins with a personal interest it presents a conflict of interest. Tech is nothing but a huge conflict of interest. You can compile the same information yourself by reading posts. In fact I was on tech when information for the book was solicited, it was like wiki.. anyone can add to it and it doesnt mean it's correct.

There is an old saying.. fool me once shame on you, fool me twice shame on me

I had a built 427 with 14-15lbs of boost. Took it to the race track running race gas and was really doing some heavy duty racing/practice. Well my block cracked. My builder took my car back and didn't even batt an eye about quickly building anther motor and installing it. It could have been a bad block who knows but they didn't even really care they just built me another one at no charge. Thats why I choose a shop that stands behind its work. My car was back together and running in lees then a week.

you'd have to take that up with the builder of the OP's engine (JRE).

Your whole subversive argument is ignorant.

with all due respect to your opinion and position as a mod, the city of detroit dept of consumer affairs is taking a different view than yours regarding the advertising claims. although this battle is still in the embryo stage, they talked about escalating the case to the attorney general.

please dont shut down this thread because of your dislike of me or because it differs from your opinions. there is a lot to be learned from this as evidenced by some of the questions that are being asked.

statements that you made such as "Your whole subversive argument is ignorant" is unkind, but i still must respect your position as a mod.

the builder was GM performance Parts as this was a fully assembled crate motor, each which are hand built with meticulous pride (as the advertising claims).

Oh well I didn't really know who anyone was talking about.

You really need to be clear about our position.

You've now TWICE, that we know of, threatened legal action.

As such, there is really nothing left to say here. GM will not publicly engage a customer who is threatening legal action. The lawers at GM won't allow it.

Obviously anything they post here can be used agianst them. So I'm curious... what do you expect to gain by posting here???

What is the end result you are looking for? You've effectively tied their hands with your threat of legal action.

With all due respect, I see no reason why GM will work with you now. I'm with you, I'd love to know what is the root cause of the failure...

But from a legal perspective... you have essentially prevented GM from dealing with this directly. Their only option is to wait to see you in court.

If you're only using camaro5 to get "visibility" then you are truly out of options, and I see no reason for this to continue here.

good luck with your case. As I've said before, I believe there may have been a deficiency in the block. but your overzealous attempts at discrediting GMPP and the LSX series engines (crates, short blocks, long blocks, etc) because your engine blew with a power adder is asinine. I can see your viewpoint completely. the engine "should" have held up based off the claims of GMPP, but it didn't. You put a power adder on there and the warranty went out the window. then the engine broke and now its GMPP's fault because they have advertised what the engine and block is capable of (that has been done by other people in the world, but broke for you). It still comes down to had you ran the engine exactly as it was straight from GMPP, would it have broken? at this point there's no way of knowing. but had you done things differently and started with an LSX bare block and built it from the ground up (as you are now having done with the RHS block) would you expect it to fail as well?
and what are you going to do if the RHS block craps out on you?
not that I believe it will because its being built right this time around.

my main issue with all of this is you have taken comments about the LSX454 and LSX block lineup and twisted them to suit your needs.

can you put a power adder on an LSX454 and make 1000+hp? Yes
Has it been done? Yes
Can you take an LSX BLOCK and build it to make 2000+ hp? Yes
has it been done? Yes
Did your block fail? Yes
Is it GMPP's fault? possibly
Is it GMPP's responsibility to fix it? Not since you put the blower on it

the crate motor was built by GMPP, but your builder modified it beyond its intended parameters with the cam and supercharger.
