I have a 78 Nova, that came with a Lm7 5.3 and 4l60e, I’m new to this and never done a swap before I need to create a list of things and parts I need. So is there anyone who can help me come up of a list of parts for getting the engine and trans to sit in the car good. I would appreciate the help

I assume the motor is not in the car already? I don't know very much about this, but will try to share what I believe...at least to give you something to think about....
I believe you will need the wiring harness with the computer for that motor and figure out a way to wire all of it in to your Nova. You will likely need a new oil pan. You will need new motor mounts. You will have to figure out how to get the exhaust system (headers?) to fit in there as I believe some people reporter having some issues with that. You'll probably need an appropriate electrical fuel pump.
Maybe someone who has actually done this could chime in, but I believe the cost vs. benefit might not make sense, but it is a personal choice. Good luck...let us know how it worked out and what you did to make it work if you do go that route....

What front accessories and intake are you using? If all truck stuff then are you going to use AC? I used back plates from LSX Innovations AL11 and standard Nova mounts. I used the F body pan but I understand the Holley pan fits better. Mine fits fine but its tight to the crossmember. I used the factory tranny crossmember slid back to the rear set of holes and made a short plate to the mount. If you want to use AC then the low truck AC compressor requires that the frame be notched. I used all ICT Billet brackets with a Sanden compressor. I used Speed Engineering X Body swap stainless headers. They fit perfect. I used a PSI harness. Tanks PA4 pump inside my factory tank and a Corvette fuel filter/regulator. I have a spreadsheet with everything that I used in the swap.

As someone who also recently started doing his first LS swap, I also had a bunch of question marks in my head for "what do I need". But, before you ask for help, there are things you need to decide first.

  1. What is your skill level, NO BS? Can you weld? Can you machine things? Do you have access to a wide range of tools? Suggestions for "modifying" stock parts are minimized when we know that isn't the route you're trying to go, but many/most of us do to save money. Many will front that they're the next Chip Foose, but can't actually stick two metal plates to eachother in reality.
  2. Realistically, what is your actual, hard-number budget for the short-term goal of getting it in the car? $3k? $6k? How budget-minded you are effects our suggestions. If you're on a shoestring budget, then big-ticket items like expensive stainless headers can be replaced with some fabricated units from the OE manifolds.
  3. What accessories are you going to run? A/C? Power steering? This will help you decide if you want to use the factory truck accessories, or switch to F-body or Corvette, as it effects the setback of the motor mounts you use.
  4. What is your end goal for the car? Cruiser? Drag racing? Autocross? Daily driver? Most of us won't suggest yanking the goosebump-sized cam for a new one if all you want to do is drive it to and from the grocery store and work every day.

Appreciate your response bro, I fabricate and weld for a living so I’m able to do a lot of that, I want to daily drive it and I also don’t really have a budget I’m blessed enough to have a well paying job so I can buy expensive parts but I rather not go that route, but also not cheap. Now I have a lot of the truck accessories and I want power steering and AC for sure I didn’t even know that it would effect the motor mounts I appreciate the help.

I have a LS conversion on the horizon. A FlexFuel L59 (basically a LM7) that is going into our 36 Chev PU. I'll probably use the stock computer and wiring; which would make it repairable in almost any shop, in case anything happens to me. This is my daughters car. And other than me, has no one that works on cars.

Keep us informed as to what you are doing, as there are different ways to get there.
