I just bought a 2002 Ls1 and I am putting in to a 2001 Chevy Silverado. The old engine is out and I hope to start the install this weekend. I am right now in the middle of cleaning the engine bay and getting the engine ready. Any feedback or suggestions would be nice.I should have some pictures soon,or click on my profile .
You prette much have the hardest part done, getting the engine.
It's easier to install the engine with the intake off
Make sure you trans is out of the way
Use an adjustable hoist thingy, that tilts the engine
it's not too hard, if you can remove your engine, you have it made.
Are you using the ls1 intake and stuff, or swapping all of it over and making it look stock?
Get those pics and i'll make you a section in our member's page, it's something for those who don't have a webpage , gives em a nice link to show their truck off.
good luck on the project,
allen
very nice...just a motor or did you get a tranny with it? must plan on re-using the auto already in there huh?

btw...i thought the red fuel covers were for ls6 motors???
I boght the covers separate, project mooving on to the fuel system and wiring. The single feed line on the LS1 will have to inplement the use of a fuel pressure regulator (in line). I am most concerned about the wiring!!!
By the way, the truck was originally powered by a 4.3
Mine is the single feed line like you are talking about. I can't see it making any difference over the return fuel line setup.
:eek: I am in California. Here is some info I have just collected. Smog legal swap is a must. #1 I could get busted in one of those portable radside somg check CHP traps. #2 Even if I get away with the roadside smog checks I still have to smog the truck every two years. #3 If I ever decide to sell the truck I will get peanuts for it because it wont pass smog.
Got some info from a shop In the area. The rules go as follows:
Can't put a heavy duty engine in the truck if i was not availiable from the factory
Must satisfy all OBDII functions (Evap, EGR, cats, AIR pump etc.)
Must use all the smog control equipment the PCM was designed to use (fuel tank pressure sensor, evap cannister, rear o2 sensors Etc.)
Intake and exaust must remain factory or need a CARB EO number.
Must pass tail pipe Emissions
I'd have to move. There's still room here in Texas!! :thumb:
theres a dealer in Arizona that installs LS6's in NBS silvy's...you could always use that as an excuse :lol: :thumb:Quote:

Her is the new plan. Found a local shop that works on fuel injection wiring, The shop will take the body connectors from the 4.3 and the engine harness from the LS1 and graft the two together.
Any suggestions
The shop specializes in smog legal engine swaps. The mechanic I talked to swears it will pass smog.
Looks like I will be spending $550 on the wiring grafting, I will be taking both 4.3 and LS1 harnesses in to this shop later this week (payday)
Open to sugestions from any body that has done an LS1 swap
Painless is only $508 shipped. and to your door in a few days complete with VATS bypass and all. ask me how i know :D
turn around and sell that harness you got from the f-body on ebay...i got $160 outta mine, so really i only paid about $340 for my painless.
Looks like I will soon be dealing with Dynatech
Hey, great decision on Dynatech, I've been chatting with him and he's really into his customers. He's honestly here to help out.
So what are they doing to the harness? Are they leaving the 4.3L pcm or just going with the LS1 pcm?
What's you timeline and when do you expect to complete your swap.
The results are going to be well worth it!!!
good luck,
allen
We have done a couple of silverado V6 to LS1 wiring convertions. I noticed your main concern is Smog compliance.
We can make this work for you and pass the reffere test with 100% OBDII compliance.
Read your information about the engine swap. Are you sure you cannot put in a better engine into your truck if it wasn't available from the factory in that year? I'm from California too, and want to install
an ls1 into a 95-98 gmc truck. Will I be able to do that?
This thread is 7 years old, the member was last on here; Last Activity 10-23-2003 12:59 AM. But someone else will be able to answer that for you.
have fun i'm doing the same to mine as we speak, my 99 silverado rcsb was a v6 and is now a ls1 power house with no motor mounts...i'm curently waiting on the v8 mounts to get the motor off of the frame then the fun hopefully will start.
