Has anyone done a TJ rubicon 5.3 vortec swap and kept there manual trans?

Hey guys. I have been debating on doing a 5.3l vortec swap in my 03 rubicon for a while now. Its a manual nv3550 and I have yet to see anyone do it and keep there drivetrain. every one I have found via search function and googlefu have came up with none rubicons or they are 4l60e swaps. I dont want a auto and I know novak makes a adapter to keep the nv3550 in my rubi. Im just trying to find someone that did it and see what issues they had... Thanks all.

I kept my AX15. Should be pretty comparable to your swap. Been beating it like it owed me money for a year now, and it has held up fine. I'd say go for it. I will say it is a total pain in the butt to make it emissions legal and run right with the manual though. I would probably consider an auto next go around for simplicity.

I just put in an 04 LQ9 in my 06 LJ Rubicon and I kept my NSG370 6 speed. Used Novak adapter for the tranny to engine. I was able to keep my transmission in its stock location by pounding in the corners of the firewall, watch out for your heater core when doing this. Ask me how I know. This allowed me to keep both driveshafts, engine skid did not need to modified, and left plenty of room for electric fan. You will be happy if you switch.

Hey 4x4=life, I got your PM about the springs I'm selling. Just wanted to let you know your PM inbox is full and it won't let me respond to you. Clear some messages out and let me know when you have some space. Thanks!

It's not tough. Check all the adapter supply places and pick one. If you are lucky, you can even fine tune the fore/aft motor position to not have to mess with new drive shafts.
