you really should have started a new thread. There are several universal wiring harnesses both GM and aftermarket available depending on what whether using cable or electric throttle body. You should swap to electric transmission at the same time. The 4L60e is about the same length as the T400 you have now. You could repurpose existing warning light or add small LED.

I would install a 500 Cadillac engine in a Chevy truck but never install a Chevy engine into a Cadillac. Especially a real Cadillac. Hope it works for you.

I'll just pick up an engine cover out of a CTS so I can have a Cadillac engine cover. I'm also thinking about building a Ford 9" so I can change my gear ratio & have a rear end that I can actually find parts for. I'm already gonna raise the transmission & drive shaft tunnel so the higher pinion won't be an issue for me.

I’m just finishing a 1964 Deville for a customer I did disc brakes at all 4 corners,installed a LS1 from a 2004 corvette and a 4l65E transmission I just fired it up 3 days ago,I had to get someone to remove security files from ecm for it to start and stay running also remove d emissions file I would post pictures but I don’t see where you can on here.

Any updates on LS swaps ?

I have a 1968 Convertible and am thinking about doing a LS swap. Looking at getting a 6.0 LS and rebuilding it. I just cruise in the car so I don't have plans of any power adders or high horsepower. The vehicle is lowered and maybe some day I will install an air bag system. If I got with air bags I would like to be able to lay it down when parked. I have a 5.3 in my 2004 suburban and that seems to power it just fine so a 6.0 should be plenty for my caddy.

Will a 4L60E fit in a 68 caddy?

I started a 6.0 with a 6L90 swap yesterday in a 63 convertible. I would love to see a picture of your engine mounts. I know I am going to have to cut the floor this trans is huge but yours looks great.
