What is the price of this engine?

We've been discussing the 2 LS#376 engine options for a while now.
That's one of the biggest reasons we all want it.

Holy snikies!!!

I tell you right now....if my 5th Gen comes w/ an LS3, I'm going to make every attempt at ordering mine w/ a factory installed cam like this one. It's going to kick all the others @sses! Sheat, yeah!!

i'm with you tag.

that was my first thought when mythic posted the link a couple of weeks ago.

I'm kinda ignorant when it comes to whats under the hood but wouldn't a cam hurt gas mileage?

What are the benefits of installing a performance cam to my future stock engine???? I heard under adding a cam requires extra engine upgrades and can hurt performance if not done right.

Can someone answer these quick questions in Laman's terms?

if i do get the LS3 version, i wil begoing with the LG motorsports cam. Im hearing guys with full boltons, headers, this cam, and a tune making over 550 RWHP in the 08 vettes.

If you have GM install thier Hotcam it wont void your warrenty as were an LG motorsports cam will.

Hell, yeah! Could you imagine? And a cam upgrade wouldn't be that expensive either! Heck...you could buy aftermarket, have a buddies shop put it in, void the warranty on the engine, and suffer the consequences when something goes wrong..... OR, we can do something like this! I just hope that it would be possible for us to order it like this. All from GMMP....all under warranty. Wouldn't that be sweet if you could do this and have it be a one of a kind?!?!
Probably won't help on gas mileage.
benefits? HP!!!
Adding a cam (depending on the cam and specs of the engine) might require upgraded springs, roller rockers, headers, etc, etc. This does not sound like further upgrades are necessary.
Performance being hurt? Heck no! Unless pinky the brain installs it for you.
EXACTLY. I'd go with whatever GMMP sells and raise that HP an easy 50hp for a few hundred bucks.

no guarrantees here but just maybe its the one.

I want this cam, but I also want some name brands on my Camaro. I'm not talking about tearing up my motor unless GMPP will work the insides, but I do want my audio, bolt-ons, rims, and tires to come from the best out there.

So should I get a cam swap first before I modify exhaust and add forced air induction systems (superchargers) ?

Do it all as a package. All those pieces work together and it is critical to have performance matched components.

Translation: Find a good high performance shop, tell them how much power you want and they can specify a package...Cam, headers, supercharger, etc.

But, kiss your GM engine warranty bye-bye. :wave:

lol damn. Oh well. I'd rather sacrafice my Camaro for individuality than to be mundane. I'm not knocking on the purist crowd, its just personal taste. Shit, its that crowd that usually sell their Camaro's for 70-120k when they turn 50 or 60 years old.

Can you say retirement?

:word: to the entire post.

this engine should fit in a 3rd or 4th gen right???

I believe most of it should be a straight sway, physically. You'll likely need electrical connections, fuel connections, and intake manifold (among others) changes to a 3rd and 4th Gen., but the Gen III and Gen IV are nearly identical on the exterior (except for things like cam, crank, and knock sensor changes.)

IMHO, this is the exactly reason I'm trying to wait for a top dog model, so I don't have to spend $1K on mods' that will void my warranty. Regardless, there isn't anything quite like the sound of a cammed V8 though.

Ya.. You cant just toss a cam in a stock ls3 and get 50 extra HP for a $300.

You need to do ALL the supporting mods first. And don't forget the custom tune thats about $500.

O ya.. and I would go with thunderracing. I loved their 224/224/114 cam in my LS1. with all the supporting mods, I got 395RWHP. and they have the best customer service too.

how easy is a cam swap compared to most other engine mods? Is it recomended for gearheads only or would it be possible for someone with basic knowledge to do?

I did my own cam swap with basic tools at my house. I did a lot of research, and took my time to make sure I did it correctly.

I pretty much learned how to work on a car by moding my 02 camaro. I did everything but tune it, and weld in the sub frames. Spend your money on tools, not install fees at a shop. And take the time to teach your self, its worth it.

Also If you plan it correctly you will end up doing the easy mods first and get better with a wrench along the way, so by the time your car is ready for a cam, you will be able to install it your self.

It’s not difficult, it’s just a lot of work. You have to remove the water pump, timing chain, intake manifold, valve covers, rockers, a mess of hoses and wire. You also have to either remove the radiator and (some or all of) the grill/front clip or pull the engine out. The only really tricky part is getting the cam timing right and not leaving any leaks.

You shouldn’t have to buy any tools, and if you do they are tools you should own anyway (except the engine hoist which you can rent). An experieced freind and/or shop manual will make things a lot easier.

You may also need new, more compressible valve springs if the new cam adds enough lift to make the stock springs stack or bind. If so then you will need a valve spring compressor and length of rope to stuff into the chamber (though the spark plug hole) to keep the valve from falling in. I’ve seen kits that allow you to use compressed air to hold the valves up, but if you lose pressure, you may end up having to pull the head to get the valve out.

anything else???;) we have done this to our camaro, this sounds right...its a lot of work but its worth it to have a knowledgeable friend there to help out because if you screw it up, you have to do it again....:mad0259:

ok then, i say we just let gm save us all this work and let us order one from the factory with this cam. :D



who is with me???

2nd

3rd!!!!!!!!!!!

thanks
 

Thanks for the link awesome motor. If it makes it in the new Camaro
it better have 19....teens in the back :bow:

I hate to break it to you, but it will be a cold day in hell before the "hot cam" is factory installed in a Camaro because it wouldn't pass emissions. you may as well say you want to order your camaro with a 572 crate motor installed.

Also, you don't always have to pull the motor to install a cam. on a 4th gen, you just need to move/pull the radiator to get the cam in. of course that may be different on the 5th gen, but who knows....

this should give you a good idea of what is involved with a cam swap....

i would kill for a camaro with a 572 in it, but we know that aint gonna happen either, if any thing they could put the camshaft in the trunk, and we will install it ourselves when we get home!!!:thumbsup: :thumbsup:

Great link, I'm new to GM so I've never seen those rods to hold the lifters up. That is a neat trick.

I used this link as a guide when I did my cam install. everything went very smooth... only tool i added was the Crane Cams Valve Spring Compressor Tool, it saved me A LOT of time. well worth the $120 even if I only used it one time :)

Thats not necessarily true. The "hot Cam" is part of a GM issued crate engine.

Possible Applications*

·It looks like "just an LS", but you know the truth
·Give your late model Corvette a new lease on life
·Update your fourth gen Trans Am with a LS1 replacement
·Don't forget the GM Performance Parts controller and harness specific for this application

The late model Corvettes and 4th Gen listed would have to pass emmisions

The LS3 and LS373 use, according to the GM Tech sheets, the same
Block: P/N 12584727
Comp Ratio: 10.7:1
Rocker Arm Ratio: 1.7:1
Cylinder Heads: P/N 12598594
Connecting rods: P/N 12617570
Pistons: P/N 19165089
Valve size (in): 2.16 intake / 1.59 exhaust

Main Differences
LS3 Camshaft P/N 12603844 - LS376 Camshaft type P/N 88958733
LS3 Camshaft duration (@.050 in): 219 degree intake / 228 degree exhaust - LS376 Camshaft duration (@.050 in): 204 degree intake / 211 degree exhaust

According to the Corvette forums, some people are already getting dealer upgrades.

Looks like you would also need a new controller unit.
P/N 19201327 LS376/480 Engine Controller Kit

Caution: With the harness details I keep seeing a note that it won't run in a production vehicle unless you use all of the kit parts and that it will not run the stock gauges, you must get aftermarket gauges.
- Need to find a GM shop to ask a tech. -

If I remember correctly, the Hotcam didn't make as much power as the second LS6 (MY 2002) cam did. If I remember correcly, didn't the LS6 have more lift and a little less overlap and LSA?

I agree that GM wouldn't get a Hotcam into an OEM car but I'm sure they, if not many other companies have custom grinds that will give good power. To me though, GM engineered the engines as a package, and operate within a certain range. Typically, adding a cam will change the operating range in order to achieve maximum power, and sometimes that range goes outside of the parameters the engineers went by. Anyhoo, I'd prefer to keep things nice and simple and stay out of the long block.

To each his/her own :D

I did alot of research before selecting my cam. And the conclusion i came to was that the "hot cam" was not nearly as good as other cams on the market.

Also I'm not saying it cant ever pass a smog test, but it would be close and depend alot on how well it was tuned. But as factory installed option, it would never fly.

I think the ls1 hot cam would put out around 380 RWHP around 400rwtq. the cam I went with TR224/224/114 will/did pass smog in CA and made 395 rwhp and 390 rwtq. And it ran much smoother than the hot cam (per my tuner).

If i didnt have to worry about smog tests, or drive ability then I wouldn't even look at the hot cam, I would go much much bigger, can you say trex... LOL

The Hot Cam for the LS3 is not the LS1 cam.
My point was Never that it was the best cam out there.

But if you look at the tech specs for both the LS3 and LS376/480 the only real part difference is the cam. The block, heads, pistons etc are exactly the same. You should only need new valve springs and gaskets. And, appearantly a new engine controller kit.

Will adding a performance cam mess w/ AFM in the Camaro?

Not really. However getting a custom tune done afterwards will ensure you are getting the most out of it.

I have heard that putting a new cam in actually will disable AFM, it would be nice if they were wrong.

Do you think GM could install it later on down the road after you buy the camaro? And I'm young and not as experienced with engines. Where could you go to get the custom tune? And what all would need to be done in addition to the cams so it would all go smoothly and pass emissions.
