gee a ls9 is really a truck engine.

The 2007 Cadillac Escalade has a 6.2 L Vortec 6200 (RPO L92) (≈376 cu in) engine. It is an all-aluminum design which, while still a pushrod engine, boasts variable valve timing, a first in a mass-produced non-overhead cam V8 engine.

just as much a truck engine as a GT supercar engine.



News flash genius, the L92 IS an LS3. It has different valves and a different intake manifold. It also sports Variable Valve Timing just like the L99 in the Automatic 5th gen's. All GM trucks use a de-tuned/cheaper version of the current LSX offerings. It's been like that since 1999.



When you hear people talking about an LSX with L92 heads they are talking about the heads off that truck engine. They ARE LS3 castings with solid stem valves. You can buy a bare set brand new from GM for barely over $1,000. "LS3" heads are a few hundred more expensive for the same thing.

Sounds like the Ford GT is a great car. What color is yours? My ZR1 is black. :-D
Talk about your car being your penis extension... WOW! Raggin' on people for not having a GT just because you have a far less valuable and far more available ZR1.

The GT was more expensive than the ZR1, and the car will hold more value till the end of time. Even today, if you can find a GT for sale, it's likely to cost more than a new ZR1. In 20yrs, it won't be a contest and not just because the GT is more limited, but because of what the car is on the whole. There are few for sale and they start at about $135,000.00. Unlike most cars, modified versions are selling for even more.

It's great GM is selling the ZR1 for less, but don't count on that value growing like a GT over time. To see a car selling for nearly sticker price, 5yrs after new... That's saying something about how desirable they are. I could only find 3 for sale.

The ZR1 is an awesome car and better than most sports cars in any price range. That won't make it more valuable and GM knew it when they built it. Had they designed it like Ford did the GT, it would surely cost more than it does. Since it will have to compete with similar GM cars, the resale will suffer some.

Again, it's a great car, but it's no GT.

I paid 107k out the door. Dunno where you got 150k from. :shrug:
See above... $150,000 seemed to refer to the GT pricing. They stickered around $140,000 to 145,000 new. People initially paid over 300K for them... That's a desirable car.

The whole idea of the ZR1 was to see what kind of Corvette they could build for $100k. It's a Z06 with 25k extra in suspension, brakes, aero, and a blower. It's not supposed to be a 1 off car with only a few thousand produced. It's not what they were going for and they never intended it. If people want to compare them to more expensive cars they can have at it.

Ask yourself this. In reference to the piston, are the valves "Overhead"? If the answer is yes, it is an OHV engine. Just because your engine is overhead cam does not mean it isn't overhead valve. You are looking for "Cam in Block". Both "Cam in Block" and "OHC" engines use an "I-Head" design with the valves residing in the upper surface of the combustion chamber inside the head.
You're argument is bogus, or worse. Technically, the valve are over the block AND the head... on an OHV engine. The OHC is called OHC because the cam sits atop the heads.

It has nothing to do with the piston.

More on the rest later.

Overhead Valve does not reference the cam at all. It references the valves. Are they overhead or not? If it isn't an I-head design like most OHC and Cam in Block engines then either the intake valves or the exhaust valves are horizontal and/or built into the block itself. Think about a dirtbike or any small engine for that matter. Most of the ones that are OHV are not powered by pushrods. There were thousands of engines all using the same 5-6 basic designs long before your OHC mod motor came out. These terms have been around for over a century.

news flash genius, everyone knows the LS3 (l92)is a truck engine. it was in a truck first. 3 model years before that low revving truck engine was put into a camaro and a year before the vette, not a car engine used in a truck.

$150K+ for a lousy Ford is any better? Much less one with a supercharged Ford truck engine. Lets hope the spark plugs stay in the cylinder heads.



Much unlike Ford, the Corvette has modern racing heritage as well. One of domination. One where Ford has NOTHING to offer for competition. NOTHING. GM doesn't have to refer back to 40 years ago to show a win, they can look at what's currently happening.

LOL....Try doing some research before putting your foot in your mouth!!

you chevy guys act like your on a ford site where nobody knows anything about your motors. like you are setting anyone straight. nope not really happening is it?

i am a huge fan of the LS2. i like it more than a coyote. more than anything out there. and yes i have researched plenty about it. my next car is going to have one in it.


you are not going to come in here or any other modular site that i'm on and think your gonna tell me one stinkin thing about modulars. or ls2's. or SBC,BBC,BBP,BBF,SBF, etc etc etc.


with enough boost a tiny motor can outpower another. In 1986 the BMW M12 1.5L inline-4 in the Benetton F1 car made ~1300hp in qualifying trim. During qualifying they were running 5.5 BAR of boost. That is 80psi.

Wow. You might be the biggest idiot I've ever met. The L92 is an LS3 with VVT and a different intake. That is FACT. The LSX series debuted in 1997 in the C5 vette with the LS1. The LSX architecture was not used in a pickup truck until the GMT800 chassis came out in 1999. Literally all of your information is wrong. The L92 was designed off of the Gen IV architecture. It wasn't a precursor to the LS3. The LS3 isn't a truck engine. The truck engine is a de-tuned version of the LS3. They limit power by using a restrictive intake and a smaller cam. They set the redline lower because the intake makes more power in the low end and mid range which is where it should in a truck. The LSX was designed for the corvette and GM adapted it for use in everything they made that used a V8. Since 1999 Every GM pickup has been LSX powered. The 4.8, 5.3, 6.0, and now the 6.2. There were several different version of each. LQ4, LQ9, L92, etc etc. Nothing designated "LS" ever came from a truck engine. Go laugh at yourself now.

Are you 15 or something? Read what I said about your last post. You have NO idea what you are talking about. You think the LS3 stems from a low revving truck engine. People like you are the EXACT reason I post here. You spread false information with overconfidence and some random guy is going to think you know what you are talking about. Later on someone is going to set him straight and he is going to feel dumb because of you. The bottom line is if you don't know what you are talking about don't open your mouth.


Also, the LS2 is the least impressive engine in the LSX lineup. You know everything about LSX's so you would know that the LS2 is a Gen III/Gen IV hybrid that uses "Old" LS6 #243 head castings on a "New" Gen IV 4" bore block with a 58 tooth reluctor wheel timing setup. The only thing good about the LS2 is it's ability to accept the heads from bigger engines because of it's 4" bore.



You think you don't need to be set straight but in reality you ARE the person that needs to be set straight. You know just enough to get yourself in trouble.

please you sound foolish. really you do. the things i say are meant to be understood in the standard english meaning. twisting words to make yourself some kind of genius is reduclous. you sound rediculous and are taking words written on a page on the internet too seriously.


get a grip. i mean seriously. get one soon. a grip that is.

And are you fawking serious? You run 13.2 @ 106 with all your mods, your own admission.:lol: Please do some research on what these cars run with bolt-ons before you spew anymore Bullshit.:nono:

right on kdw 2's... spinning the hell out of first and second. with a 2.2 60 ft..... you're such a jackass. just because i ran a 13.2 spinning doesnt mean i wont take out a ls1 that ran a lower et with traction. the time doesnt mean shit, the trap will tell you everything about a car and how fast it is. a car that runs a 12.50 at 106 and a car running a 13.2 at 106 will be dead nuts tied from a roll.

sorry i didnt have drag radials when i went to the track but she will run in the 12's at about 110 on a good tire

You are correct..though I don't exactly live in the greatest place on earth when it comes to track conditions/DA... So I see what you are getting at...

Summer Time...
13.4 @ 104mph 2.1 60ft @ 3200DA

In SFL the DA is not as bad as your, usually between 1700 and 2100(from the times I've gone to the track. I've only made one pass to see how it felt and ran 13.0 @ 114+ w/ a high 2.1 60ft. on street tires and full weight.

:lol: Your kidding right?

I dont recall posting a "j/k" after my comment. Im not at the track every day and when Im there Im not looking for H/C LS1s, but the times I have seen them/talked to them/overheard them talking, those are the results I've seen.

That's a far cry from your "gears and DR's only" statement. After seeing what was actually done to it, it makes sense now.

It wasnt the same one I was talking about. I just happened to find another one. Still, gears and DR's only I wasnt even sure about. I still remember that it wasnt very many mods that he ran 11s with.

See you just showed how biased and/or ignorant you are. You said LS1's make it into the low/mid 400's N/A (trying to compare them to mod motors). They can do that cam only. An average budget heads and cam car makes the same power I'm making. I OWN one. Plenty of people make well into the 480's on stock cubes. You can make over 500whp on 346 cubes while staying hydraulic roller if you put together a well thought out combo and don't cheap out on the heads. It's been done over and over. There's actually a giant sticky on LS1tech titled "The recipe for 500whp N/A with Heads and Cam." If LS1's only made mid 400's the Stock bottom end N/A record wouldn't be mid 9's would it?

And there is a guy that just posted a thread not too long ago right here on svtp about a 5.4L naturally aspirated modular motor that he built and it made over 700 hp at the wheels.

Its easier to make N/A power in a pushrod cuz it only has one cam(which happens to be an achilles heel for it) and its easily accessible to change out. You could almost call it a bolt on mod. That doesnt mean modulars cant make big N/A power because they have. That doesnt make the ls1 better.

See, modulars are > than pushrods for many reasons. They have better block strength and they can make ridiculous amounts of power. Power that an LSx block can only dream of. Its really laughable that there are guys in here that really think the LSx block is the best thing ever made especially when you start trying to throw any real power at it the whole thing just splits open like a walnut.

Another disadvantage is pushrods only have one cam. DOHC modulars have 4 cams that are also located on the OUTSIDE of the block. Not only do you have unprecedented control over engine timing like never before but you can evenly distribute boost across all 32 valves(something else pushrods cant have) allowing you to have crazy amounts of boost making crazy amounts of power. Like how about 52 psi of boost out of a little stock size 281 cubic inch motor that pegs a dyno at 2000 whp and who knows how much power it was REALLY making because the dyno couldnt go any higher than that. Find a GM motor that can do that.........oh wait, there isnt one.

with me (150lbs)...

3590lbs

Not a huge difference really.

Haha, S8ER, I stand corrected. Its closer than I thought.

Even if I paid 107k out the door like our arctic friend did for a zr1 I would still rather buy a c6 ls3 and spend the dough I saved on modding it to be better than a zr1 and still save some cash........plus I wouldnt have that guady plastic window on the hood showing the guady plastic engine cover....

Quit trying to pass off false information and opinion as fact.

ditto man. im saying the same thing back to you that you are trying to pass off and you think im passing bad info.

you said a GT motor is a pickup truck motor thinking you were slick and would get to someone.

i said the exact same thing back to you by calling a vortec 6.2liter (l92) an ls3. and you go off the deep end telling me im passing off bullcrap.


in fact both basic architectures(modular/LS?VORTEC) are used in multiple platforms.



so all that has happened here, is i'm feeding your crap right back at you and you cant handle it.


re read everything i said. you fell into it like an 8 year old. too easy, just like arctic00. just easy to get you mad. so i enjoy taking you down that road if your gonna fall into it.


you told me NOTHING i didnt already know. NOTHING.
