I'm starting my LSx build on a gen I LS factory V8 auto that I picked up cheap due to it having a bad motor and a slipping transmission. I've done some digging in the LS1 swapped LS that's been on this forum for a while, figuring out what issues are going to come up, but it seems pretty straight forward. I've got the engine electrical disconnected from the body and everything seems to still work.(power windows/seats, lights, wipers/delay, climate control, etc) Stuff not working with the wiring unhooked was my biggest fear when I bought the car for a swap. I'm aware that the dash and gauges will not work but I'm ok with the aftermarket gauge route. So once I get the motor out the fun begins. I'm going back in with cast-iron LS series motor out of a truck and an automatic trans. Here's the "basic" parts list, I'm aware that many little parts will also be needed, some of these I already have some I have located to pick up this week. Here's a picture of the car too, I'll get more after the motors out. -2002 LM7 5.3 which I already have, or a 2005 LQ4 6.0 my buddy's got if I can scrape together the extra money for it. -Turbo 400 auto trans -1999 Cobra 8.8" Rear End -Custom Driveshaft -Mounts -Custom Oil Pan -Harness/ECU got the harness about built just need to get my ECU tuned. -Gauges I do have a few questions about the 8.8" swap though. The factory 8" is a 28 spline output and the 99 Cobra 8.8" is 28 spline both with pretty similar housing. I know I will have to build custom front mounts for the Cobra stump. The only question I have is will the axles fit? (are the stumps the same width I mean?) And the rear diff cover from the 8" will fit on the 8.8" right?
