So your planning to take out the old motor and have the LS one swapped and all buttoned up in a weekend? That's great ! Just make sure you have the LS harness done and ECU vats removed before hand. Theres are alot of little things that delayed me. But then again I did not have everything from the 5.3. I had to get all the accessories harness, ECU all thru Craigslist, eBay and local junkyards at the time. It freaking nickeled and dimes me to death ! A few things that may also may help you out that I can recommend: Use an LS1 (Camaro) three wire temp sensor. It wire to the 5.3 original location. Two wires go on LS harness one goes straight to the OBS temp gauge cluster. Using the 5.3 fan clutch till you want to get electric fans will work fine, less wiring. Find a way to mount the OBS a/c compressor. OBS radiator will work on the 5.3. Triple Check all ground contacts if you can't get it to start once everything is swapped in. Hope this helpsIm at a budgetary stopping point at the moment but the torque converter is here. I need to get plugs wires and some sending unit adapters and we will be sliding the TBI out along with the tranny and sliding in the 5.3 and the 2001 4l60e. I'm thinking the weekend after the 4th of July starting on a friday night and finishing on sunday night. That should give me 2 weeks of around town driving on it before I make my first trip with it.
Good question about the sensor. Yes mine is off by like 30 or so degrees. Reason being, was that when I sent my ECU to have vats removed and tuned, I did not tell Brendan from lt1swap.com about it. I got the ECU back and by that time I had already went with the Camaro temp sensor. If I would've told him beforehand he could've simply made the change when he programmed itThats definitely an ambitious goal for sure, I hope you succeed. I can't remember the back story completely but I would try and have a back up truck for Monday morning just in case. I've been reading up on ls swaps for years and I've yet to see one go as smoothly as the swappers intended. As far as the a/c goes, I intend on using lextech's bracket kit. I have already purchased and installed some of the kit. If you would like some pictures of the kit let me know.
Dgonz does your 3 wire temp sensor read accurately, I thought I had read somewhere that they worked but read inaccurately? ( I know, kind of contradicts my years of ls swap research comment but I think I've done too much reading on the matter. Sort of researched myself in circles)
What JD mower is that? Sorry for being off-topic, but I sure love my JD mowers...Got the heads on last night. Intake and some of the wiring and smaller things will be going on tonight. I am still waiting on the torque converter but I am pretty close to ripping out this gutless 5.7 TBI
