There was some interest in the few LS swaps I have done so I'm going to start a thread for questions and I can post some Pictures of things if people request them. My first LS swap was a 1984 CJ7 with a LS1 from a 2000 WS6 5.7L and now has a 4L60E behind it. this one I uses a PSI conversions Harness since I wanted to be able to put the ECM inside the cab and the harness was long enough to do that. I used a Alluminum radiator from Novak Conversions as it was a bolt in using with trans cooler from them. and I used a Built 4L60E from them that had their adapter tot he Dana 300 T case and one of the things that became an issue when I was running the th350/Dana300 was getting a VSS (vehicle Speed signal) to the Ecm which is critical for correct engine operation and not to mentions trans. I tried a couple speed signal generators which didn't work. and when the Th350 gave out I bought the novak trans that had their version of the 40 pulse tone ring built into it in the tailshaft of the trans and problem solved. Since this motor was a drive by cable that was easy to connect to the jeep pedal. other things included sanderson blockl hugger headers for tight fit, customer driver shafts but enough about that one.
I have had this 1986 K10 since 2000 when it had 50K original miles on it. it was a 4 speed 305 truck Silverado with air and cruise. when I bought it had a 350 vortec but carb motor. it sat for almost 10 years from 04 to 2013 when I dug it out of the barn ad began the swap. firs I pulled the front clip and the motor and 4 speed trans/tcase and I bought the Dirty Dingo adjustable mounts which I suggest since they have 2.5" of front to back slide adjustment. and also bough their air conditioning compressor setup to use a sanden 508 compressor and the air works great with a couple custom hoses. you can't use the factory compressor due some incompatable operation and you would have to notch the hell out of the frame to use the stock location on the side of say an LQ4 block which is what I obtained. I bought a wreck 2004 2500hd 4x4 from work for 2200$ with 9,449 miles on it is all. (and operator tipped it over in a trench)
I used the factory harness from the engine and used a guide from LT1SWAP.com on what wires to removed but if you use this don't take the oil pressure sensor wires out (IDK why they have you do that but I could have picked up the oil pressure with my Dakota digital dash off the data port and instead had to run a wire and a sensor to the back of the block. the best way I found to mod the harness is to leave it on the engine anchored with all the clips and start at the ecm plugs and unpin all the wires form the guide on LT1Swap.com and then start pulled them out back to their plugs and try to keep all the wires in their clips this will make it much easier to table things back up and make it look neat and original. the guide also tells you all the Pink, Orange, and black wires to separate and connect together for grounds, keyed power (pink) and constant power (orange) and how to connect them to a fuse block. also the best way I figured out to ignite and shut down all the relays and the ecm was with the battery wire that used to goto the distributer. (worked great)
anyway so here is a start ask any questions you want or for any pictures you want and I will take them and post them. have done a 4WD (mine and a 2Wd (a friends) which he did a lot of it himself. also if you are doing a 4WD there is two pass side drop front drive shaft factory t cases that can be found that already have the VSS in them that will work perfect for the VSS form any GM ecm that requires 40 pulse per rev signal. Hope this will help. these were very fun and rewarding swaps:thumb:
