Re: Calling all LS1 converted trucks.
Any chance of a stickie or a place for all the GenIII swap threads...?
Love this stuff... |
Re: Calling all LS1 converted trucks.
I've been subscribing to all of them in hopes up updating my swap thread later on to include several links to this forum for info, but haven't gotten there yet.

Re: Calling all LS1 converted trucks.
Alright, another question.
The other day my check engine light (CEL) came on in my '01. Car was running just fine, but an injector clipped open for a second. No big deal. However, without the CEL how would I have known there was an issue? I'm assuming you guys are swapping clusters as well - so how do you get around this? |
Re: Calling all LS1 converted trucks.
CEL = MIL ( malfunction indicater lamp)
the computer controls the ground to the light in the cab, or car... so you mount a light of sort (LED, perhaps) to the power sorce and the other side is connected to the computer (ground, when a malfuction occurs).... you also connect the DLC (data link connector), the thing all mechanics plug their computer into , to read/diagnose engine problems... |
Re: Calling all LS1 converted trucks.
wow, great thread!

Gotta understand, check engine light is just an LED or small light with a pretty graphic over it. Just like everything else in the stock car harness, it has a wire that feeds it a signal, and the light blinks (CEL - check engine light). Speartech and several other places sell a DLC (diagnostick link connector) and harnesses are hacked to produce two output wires: 1 is for the CEL light signal, 1 is the diagnostic data line. You provide the ground wire and the constant power, and voila - instand diagnostics light and line to send codes over. You can get the DLC connector (diagnostic link connection = DLC?) from Speartech @ www.speartech.com. This is what you pick the code scanner up to. It's all about retrofitting. Figure out how the original car works, then replicate it :D |
Re: Calling all LS1 converted trucks.
Shifty; so are you saying I can use my original gauge cluster?

You'd need to convert your tranny to use a mechanical speedometer (this is possible, but more money than I would spend). There is a spot where you can drill your oil pan and tap it to use the stock mechanical oil gauge. You can T-off of one of your vacuum lines to hook to your vacuum gauge. There is a bolt hole in the rear of the passenger side head you can adapt to use the stock mechanical water temp gauge. Your stock gas gauge will work fine with no modification. Your stock ammeter gauge will work, with minor rewiring. You will need an electronic tachometer, though. That's about the only gauge you really need to replace - and only if you really, really want one. I'm telling you, with this swap, all you need is a 3-digit IQ score, some creativity, the ability to read, and the common sense to know when you should look up the answers on your own, rather than ask someone who has done the swap :D --- I say this because --- If your experience is anything like mine, asking people who've done the swap a lot of simple, easy questions up front makes them less likely to answer the tough questions and help with your problems later when you will really, really need the answer from someone who should know :D Google is your friend. LS1Tech's "Conversions" forum is your friend. Good luck with your swap. |

Very weird. I want to use the 3-gauge dash, with either: a) one 5" speedo/tach combo with one 5" quad-gauge (oil/fuel/water/volt) and leave the center gauge intact or b) one 5" speedo, one 5" tach, and the 3-3/8 fuel, and find an add'l mounting location for smaller 2-1/8" (I think?) gauges for water and oil (I drew it up with them mounted in the bottom left/right corner of a 3-gauge dash) I might relocate my headlight switch elsewhere and put the other two smaller gauges in the holes for the headlights and choke,respectively. b) one |

Re: Calling all LS1 converted trucks.
Well I finially got me another engine and trans. I ended up with a 4.8 and a 4l60e. What motor mounts are you guys using for the ls motors and what did you do to for the trans crossmember? I am going to turn the 4.8 into a iron block ls1. I got my pistons in yesterday and the crank is on its way. I am trying to locate some 243 heads and a ls6 intake and a tr226 cam. Also what accessories are you using on your motor (car or truck)? Are you using the truck oil pan? I hope the engine combo will make some good numbers and still give me around 18mpg.:burnout:

Re: Calling all LS1 converted trucks.
Try this for the crossmember! http://www.performanceonline.com/sto...cat=455&page=1
From what everyone tells me you have to have the truck oil pan for clearence purposes. |

i went with ECE - they do put the engine a little par forward, if you are using the truck engine and plan to use the mechanical fan, this may be a problem for you. i DO NOT recommend using the crossmember linked above (it's the same unit that ECE sells), I believe the tubular crossmember that CPP sells is a much more attractive, slim and easier-to-install unit.

EDIT: I am saying this b/c i tried to skimp on my wiring. i thought, "hell, why should i pay an add'l $300 to have someone else hack my stuff. well, needless to say, NOW i understand. would have shaved several dozen hours off my project. $$$$ buys you time (saved). just remember that. |
Re: Calling all LS1 converted trucks.
I just got my LS1 in my '70 running. I used the tubular perches from Brothers and the adapter plates from Advanced Adapt. I had to move the perches back about 3/4" from stock location because the factory Z28 pan was hitting the crossmember. I used the factory trans x-member and just slid it back and re-drilled mounting holes. I've taken it around the block a few times... seems to be working good.
