Hi all,
since being away from florida i am in rhode island currently at my uncles home.(man i love this state) but anyway he just sold me a 2002 LS1 that only has 2000 original miles on it w/ the computers and tranny (auto) for(get ready to hold onto your shorts here) 2500.00 i didnt hesitate to buy it.Now my question is can the original th350 crossmember work on the tranny? I am so excited cause he was gonna use it for his 55 chevy and he is sticking with his 60 over 350 and muncie stonecrusher.He said the motor is rated at 565 hp and i heard these motors are all that n then some.Is this a better build then a big block?t has everything including the power steering pump and serpantine setup.This will put a huge dent in my build for drivetrain.
thanks
pat

I don't have an answer to your question but I'm really excited for you getting that motor. My friend and his brother both have 2000 ws6 trans ams with that ls1 and man oh man are they fast. Well good luck..Jeremy
-
565 HP? Where did he get that # from? I think the max those were rated at were 350 HP the LS7 is supposed to be somewhere around 500HP
-
LS1 or and LSX? What size is the engine?
I am putting a 6.0L in the 73-87chevytrucks.com pickup documented here. The tranny crossmember will work, you just need to swap out trans mounts, you will also need motor plates to bolt it in... Check my post for more info.

This motor came out of a 2002 LS1 corvette. Thats what he showed me on his receipt and that this motor only has 2k original miles.
thanks
pat

I think the 02 vette had the 345hp LS1....565hp?? maybe with the biggest cam and best flowing heads with full bolt ons My buddy put down 465rwhp with his 01 Formula LS1 build and that was about as radical I have ever seen on a LS1 in my area.
My stock 99 Transam LS1 put down 286rwhp totally stock on the dyno.
At any rate a LS1 swap is alway kewl!! post up some pics if you get any.
-
If it came from that 'vette, it may be the LS6, it was rated at 405hp. $2500 is pretty good(especially if it's a LS6), I usually see them for $3000 without trans. I think it's better than a big block if you plan to drive it on the streets, it'll get better gas mileage and you get the "cool points" along with the nasty power. Good luck with your swap.
-
i almost did the same swap when i first bought my truck but its a project! theres a few things you have to get/change.... you need to get a bracket that moves the a/c compressor to the top right side of the motor because its in the way of the frame... you need the exhaust manifolds from a camaro and since the throttlebodies on a vette are fly by wire you need to get the peddle conversion to convert to fly b wire... OR you can just get a throttlebody assembly from an ls1 camaro... post it up in the members project section... i would love to see how it turns out for you since i didnt get to do it with my truck!
oh and i'll look for the info on where i found the ls1 install on a 73-87 it has everything you need as far as parts and stuff
-
I too think it be a better setup then the big block i wanna originally use.He said this truck after its installed be 1 truck i dont think anyone would mess with.But since the truck is in pieces right now i think it be the right time to get it mocked up and see how it fits while theres no nose on it.But when i get back from my vacation i am gonna get back into getting the front suspension together and assembled and painted .
thanks
pat
p.s. by the time the big block was gonna be built and the 700r4 was as well i wouldve been doubled with what this setup wouldve costed me already.
-
the LS motor will be much better on power and on gas. You can see what one looks like mocked up in my topic I linked above.

I thought the 6.0 was an LQ4 or LQ9, the LS family is different...
-
The LS1 shares little other than similar displacement, external dimensions, and rod bearings, with the earlier small-block V8 engines. It is an all-aluminum 5.7 L (346 in³) pushrod engine and was rated between 305 - 350 hp (227 to 261 kW) and 335-365 ft·lbf (454-494 N·m) of torque in North America, depending on the application.
-
I thought the 6.0 was an LQ4 or LQ9, the LS family is different...
No, LS motors are the generation of engines; Gen III and Gen IV. ALL 4.8, 5.3 6.0, 6.2 and the 97 vette 5.7 (LS1) and 7.0 are all LS motors.
LQ? is the RPO designation of the motor.
4.8 = LR4 (GIII) or LY2 (GIV)
5.3 = LM7, LM4, L33, L59 (GenIII) or LH6, LY5, LMG LC9 (GenIV)
5.7 = LS1, LS6 (GenIII)
Truck 6.0 = LQ4, LQ9 (GenIII) or LY6, L76 (GenIV)
Pass 6.0 = LS2, LS4, LS3, LS7 (GenIV)
6.2 = L92 (GenIV)
7.0 = LS6
-
Regular Production Options ?? NO the LQ4 is the engine code... Guess you didn't research much, here ya go...

I have done WAY more research than you have since we turbocharge these. Apparently you didn't do enough research. I wouldn't post information unless I am over 95% certain and I am 100% on these.
LS engines are designated by the 4 head bolts, 6 bolt mains, coil-on-plug ignition, and 1-8-7-2-6-5-4-3 firing order.
You are still wrong and the links you just posted proves it,, might want to read them first instead of just quoting pieces...
ALike the LS6 before it, the RPO code of the LS7 pays homage to a previous GM big block.
B
The cylinder firing order was changed to 1-8-7-2-6-5-4-3, so that the LS series.
C
The LS series was a clean sheet design, drawing on the heritage of the classic small-block, but is all-aluminum and has 6-bolt main bearing caps.
D
The LS engine has been the sole powerplant of the Chevrolet Corvette since 1997, and has seen use in a wide variety of other General Motors vehicles ranging from pony car to full size trucks.
E
The engine blocks were cast in aluminum for car applications, and iron for most truck applications

Regular Production Options ?? NO the LQ4 is the engine code...

I guess not what does RPO mean? The last applications list above is for the LS1 engine.
-
What was the point with listing all of the applications?
RPO is GM's 3 digit code representing an option, be it engine, trim, paint, wheels etc.
For example the RPO for the 350 in the 1987 pickup is L05, the 305 for the same year is the L03. A 350 in a Vette for the same year was L98. Same block, same crank, same rods, everthing else was different. Same holds truck for the 305, same block (different bore) same crank, same rods.... Just like and LS motor....
If you look on the Caddy with the LQ9 engine under the option sheet it will list LQ9 = 6.0L 345hp version, just as my 1987 lists L05 on its option sheet.
For contrasting comparison, the trim levels for 73-87 pickups are YE9 for all top level trucks, and Z62 for all base model trucks.
I have been working on and around Chevy motors longer than you have been alive, I didn't just start working on them this year.
-
I thought the 6.0 was an LQ4 or LQ9, the LS family is different...
No, LS motors are the generation of engines; Gen III and Gen IV. ALL 4.8, 5.3 6.0, 6.2 and the 97 vette 5.7 (LS1) and 7.0 are all LS motors.
LOL...
First, LS is not the generation, GENIII, GENIV, etc... is the generation.
Second, until 2005 when the LS2 was introduced to the Corvette, there was no 6.0 in the LS family.
Third, although some of the parts are interchangeable, the LQ and LS designate different engine "family's". Was there ever an LS1 on a truck? Was there ever a 6.0 (LQ4, LQ9) in a passenger car?
Fourth, thanks for NOT defining RPO. What does it stand for? Regular Production Options? Obviously I don't know what I'm talking about... The LQ4,9 designate the options on the GENIII engine, the LS1,2,3,4,7 do the same, but ultimately they are different "family's".
Fifth, I listed the applications to show you that the LQ engines didn't go in a car, and the LS engines didn't end up in a truck.
Sixth, way to take personal shots, what a professional person and business man. Your 22+ years of knowledge of the Chevy engine is relevant to an discussion pertaining to year 2000 and up engine's... huh...
-
I think people just refer to genIII motors as LS family, I do. And they are related. That's why you see, LS6 intakes on LQ9's, LS2 heads on LQ4's, L92 heads on LS1's, LS1 heads on LQ4's. I just put some LS6 heads on my LM7 last month. It's the same family as far I know. I have an LS1 style intake and LS1 headers on my truck right now. And GM has put the LS7 in a truck....it's the new SS concept.
-
I actually feel stupid after reading this thread now.
Maybe we should all understand what an RPO is b4 we start quoting WIKIpedia articles. BTW http://en.wikipedia.org/wiki/Wiki
dooooyyyyyyy :P
-
Well i got some good info bout this swap so i am gonna continue to get the front suspension done and have to take a drive back to my hometown to go get the setup.DO/Will i need to cut the tranny tunnel for the auto setup?I know on the show musclecar he had to cut the tunnel for the 6 speed setup.Will a set of shorty headers be a good idea to run too?I know i`ll need to have a custom driveshaft made but the more ideas i get the more i wanna go get the motor setup.
thanks
pat
-
stock camaro/ta exhaust manifolds work so i would guess that aftermarket shorty headers for a camaro/ta would as well... they look nice too
-
Just be sure to do a some research before you buy stuff. That last little detail can make all the difference in the world. Pay attention to the motor mounts you buy, they can make the difference between having to cut/grind/relocate or just "set it and forget it".
-
Just getting back to this....
Yeah Vile. I was going to post that wiki is edited by anyone that cares to log in so its is likely to be inaccurate, but still....
1) All Gen III and up current motors are refered to by GM as LS-series. Have you heard of the LSX?
Here is a webpage from GM
http://pprod.gmgoodwrench.gmgssm.com/GMPerformanceParts/EngineShowcase/index.jsp?engId=LSX&engine=LSX&sku=19166454&engCat=ls
Please note the following sentence: Dream bigger. Because the new GM Performance Parts LSX takes the LS-series V8 to the ultimate extreme.
2) until 2005 when the LS2 was introduced the Corvette used the original 5.7LS1/LS6 (going on 8 years). Being in the same family means parts will swap from one to another it has nothing to do with displacement.
3)LS1 is the RPO for a high performance motor, LQ4/9 is the RPO for a pickup engine. It has nothing to do with engine families. They are all Gen III or Gen IV motors. Engines are assembled and designed with their intended purpose in mind. The LQ9 was designed to give a 6000lb truck some pep and allow for towing. The LS6 was designed to compete on a race course in a 3100lb sports car.
4)I did Define RPO, you had the naming correct, it is just you don't understand it.RPO is GM's 3 digit code representing an option, be it engine, trim, paint, wheels etc.
In general, all current engines from GM use L to designate engines; LQ4, L05, L33, L98, L79 LT1, they use M to designate transmissions; MN6, M22, M21, M40, M38, they use J to designate braking components; JB3, JB5, JB7, JB8, they use Y to designate interior decour package; YE9, YG3, YG5. Search for GM RPOs you will see what I am talking about.
5)the LS1 didn't come it a truck an the LQ9 didn't come in a car. You are confusing RPO with an generalization. The LS1 RPO didn't wasn't an option on a truck when you bought it, just like the LQ4 wasn't an option on the Corvette. Until 2001 the Vette only has one engine option. The trucks get 3 options.
6) I don't know where I made a personal shot, but if it came across that way please accept my appologies. We are talking about LS-series Gen III and up engines, they started in 1997 with the LS1.
This is the last reply I make so on to the original topic.
First, LS is not the generation, GENIII, GENIV, etc... is the generation.
Second, until 2005 when the LS2 was introduced to the Corvette, there was no 6.0 in the LS family.
Third, although some of the parts are interchangeable, the LQ and LS designate different engine "family's". Was there ever an LS1 on a truck? Was there ever a 6.0 (LQ4, LQ9) in a passenger car?

DO/Will i need to cut the tranny tunnel for the auto setup?
Will a set of shorty headers be a good idea to run too?
thanks
pat
Pat the tunnel won't need to be modified as the 4L60E is the same as a 700R4 (and 4L80E = TH400) which came in these trucks.
If you go with headers, I would get S&P versions. I know of people using them and they are very satisfied with them.
Also, have you checked my post on the website truck?
I am using the truck manifolds on mine, I just had to modify them.. I couldn't get the F-body versions to work like I wanted them to...
-
Heres another good question,
just reading bout a fuel pump the corvette LS1 motor had its fuel pump in the tank correct?I plan on running a fuel cell between the rear rails and will i need a internal fuel pump or will a external mounted fuel pump be ok?
thanks
pat
-
All GM EFI vehicles use in tank pumps. You can run an external pump, Keep in mind they are LOUD and the fuel actually cools the pump and quietens it down and they last a little longer.
You can run a Blazer Tank like I am doing and you can use a TPI pump to supply the fuel. If you run the Vette Regulaor, you only have to route one line to the motor...
-
If you do decide on an external fuel pump, the Walbro 255 is what a lot of NBS guys run. They make them for internal and external applications and they usually run from $100 to $150.
-
I highly recommend Walbro also if you are going aftermarket. We sell these for the 99-up Turbo apps.
-
well i found out by a buddy this is NOT a vette motor but indeed a camaro SS motor,I was told the vette motors tranny was in the rear of the car and this 1 is bolted to the motor.I will still purchase it when i go back up north on my vacation again.Sorry for the misinformation.
thanks
pat
-
Didn't the SS come with LS6 heads(243) and intake?
-
Negative, the SS F-body used the same basic motor as the Vette, but the exhaust and intake were more restrictive. (less restrictive on the SS' exhaust)
