So I’m needing help trying to figure out what all parts and stuff I need to do a 5.3 swap in my 1994 z28 camaro with a automatic 4L60E. What kind of wiring harness and computer? Do I need a new k-member? I can get an engine for it but what do I do about the brackets and mounts for the new engine? Any advice helps,

thanks

There are engine mounting brackets available from Hooker that will place an LS in your car on your stock K-member and in the same position it sits in a 98-2002 F-Body. They are designed to be used with stock 4th-gen F-Body LS engine mounts, so you can choose to use rubber or poly mounts. You’ll have to swap in a 98-2002 steering rack if you want to install headers.

If you can, I'd purchase the Holley Terminator X Max system($1500). I purchased that system without the trans or DBW tuning and I'm ready to start my swap up tonight. It comes with the wiring harness for your application, the ECU, O2 sensor, and the handheld tuner. Once it's started, it learns the motor and runs itself. It's fully expandable and there are people already making 800whp with this setup, so it gives you tons of room to grow. HP Tuners on the stock ECU isn't nearly as user friendly and you still have to buy a wiring harness ($400-1000) or tear down and reuse the stock harness on the motor from the donor. Then it's just figuring out the tuning and making it run right. I bought the HP tuners Pro suite, a laptop and quite a bit of miscellaneous stuff to set my stand alone harness up and I still ended up buying the terminator X ($1000) to use instead of my stand alone. I liked the ease of tuning and it cost less. The suite alone is $700, then a wiring harness already complete would put me over what I spent buying the Holley setup. Plus, I saved tons of time. I spent many, many hours trying to figure out how to wire the standalone properly even with the help of lt1swap.com.
