I am looking for stickies or any other articles on people that have done LS1 motor swaps on LT1 cars. I have a few deals on hand not to mention the resources to do it so I want to see what's all involved.

I know the basics like k member, motor mounts, pcm and wiring harness (one I'm looking at comes with the motor). Also the one I'm looking at comes with the 6spd T-56 I would want.

One strange thing I heard is that my interior my cause some problems? I have a 96 Z with the older interior. A friend of mine has a 97 with the newer interior so he never has any issues. This was just something I heard and I am just wondering if I would have to get a LS1 interior setup.

Just wondering if there are any really good articles on LS swaps into LT1 cars. I've googled and did a search on here. Found a good article from Merv on wiring but that was about it.

Any help would be greatly appreciated.

What exactly do you wanna know? Gauges and stuff? If you have a newer style interior, you'll be able to swap in the gauge cluster from the same year LS1 and do some minor rewiring of the harness and have all the gauges work, if not only a '98 engine harness will keep almost all your gauges functioning 'cos it doesn't use a serial data line and works on analog just like your '96. The only issue maybe the fuel gauge 'cos the different years used different reference voltages.
You're not gonna run into any issues with the interior except for what I mentioned above. There's a couple small things like turning off VATs in the LS1 PCM 'cos the older car doesn't have a body control module/etc. When I did my conversion (well, car is owned by MonmouthCtyLS7 above now), I used a '98 harness and took the time and made sure I wired it up so that it was almost plug and play and didn't need to rewire any of the interior (except for the OBD-II port). PM me if you have any more questions and I'll help if I can.

Yeah I think he is trying to make a post so we dont have to pm each other etc. So the info is available all in one post of what to do.

I asked this same question about 1.5 years ago. Pretty much, all the answers
I got from the intelligent folks was, "you're better off buying an LSx car. Unless
you're just dying to put an LSx engine in an LT1 body".

Thanks again guys. Well I'm definitely not just buying an LS1 car for sentimental reasons. Lost my dad a while back and he and I were both building my car up, wouldn't trade/sell the car for the world now is my point. So I'm tinkering with the LT1 for now and starting an LSX build, thinking LS1 or if I can swing it LS2.

WOW terrific articles Mean Green, Caldercay thanks for the info, interesting about that 98 harness, good to know thanks for the links, I have some good research now to read. MERV big thanks, that is what I was looking for, a whole breakdown. Thanks again for all the help fellas this is what I was after.

You do not need the LS1 gauges, they would be a pain in the *** to install any way. The LS1 PCM will run the LT1 gauges just fine after it is reprogramed for the tach. Only other thing you will need is a 98 only temp sensor to run the PCM and the gauge seperately(only applies if your engine harness is 99+). Even in the 97 the LS1 harness will not plug right in and work. Wires will have to be moved and the engine harness will have to be modified to work right.

Another mis-conception is the Fuel System..nothing has to be touched in the Fuel System wiring on the Car..it all works fine.
