5.3 to 6.0 swap

[Chevy-Art]

ok awsome one of my main questions is
what about the wiring?
do i need a new wiring harness? and
what about the PCM do i need the one from the truck the motor is commin out of or can i get the one i have right now reprogrammed?
will it bolt up to my 4L60E for now until i can find a 80E to swap in?
can i use my stock electric fans that i have right now or will i have to a get another set to swap in?

For wiring use your existing harness, no need to cut it up.
You can use you existing PCM, and since Allen tuned it even better for you.
The 6.0 will bolt to the 60e, amd depends on how you drive it, it should last a while.
And you can keep your fans.
Once you do the swap and look under the hood no one but you will know it is a 6.0, because the 4.8, 5.3, and 6.0 look identical.

Also for all your mods ( Future: stall, cam, 4.10's ) you can get them from the site sponsors. Nelson Performance, Circle D, and Ron's Machining Service. Since it will be apart may as well do them then.
