2002 LS1 install

[80stepsideguy]

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.

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

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...

[Nickg124]

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.

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...

A

Like 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
