Haha yea exactly. How was the 6.0 swap? Did you just buy everything in a bundle like the ecu and harness and all that? I am kinda thinking that would be a cool project to do one day.
There are packages out there for every aspect of this swap, but I am a cheap skate and waited on good deals. If you buy all the premade stuff this swap can cost north of 10k.
One place to not cheap out is the quality of the mounts, I used Ronin Speedworks kit which is basically the best you can get and utilizes the Corvette mounting pedestals. So physically getting the LS and T56 mounted was fairly easy. Just had to cut out the old transmission mount points and drill in the new mount points. Also had to trim the shifter hole a little bit.
The wiring and ecm were another story. it can cost a lot of money to buy the packages, so I bought a harness that had already been "Worked over" but needed a lot of love. Got it cheap and then spent about 6 hours repairing wiring and rebuilding the entire harness. The ecm I sent off to a guy in Missouri that dropped in the LS2 tune, removed VATS, emissions and the rear 02's.
I had to recreate all the fuel lines, wire all the gauges, custom fit an electronic speedometer, custom fit a radiator and fan. It was well worth it all though.
There is a reason you see so many half complete swaps out there. Just make sure when you start that you are in it for the long haul because you will never get your money back out of one.
