6.0 OBS Swap in California

Okay, according to California's laws, you can legally swap a newer truck motor into an older truck. New engine must have all OE Smog equipment (? on a ls). You must swap a LIGHT DUTY truck motor into a LIGHT DUTY truck (no mixing HD and LD). Cannot swap a car motor into a truck.

Now, I have an 88 RCSB with a 305 and NEW 700R4 (just installed).
I have been researching alot on LS swap and decided that I want to do a 6.0.
But I need some help choosing the motor.

-According to the Cali laws I posted, what vehicle do I want to hunt down?

-Should I make the extra effort to find only DBC, or is the DBW conversion worth it if I find a good deal on a DBW engine?

-Let's say I go with a pre-made wiring harness, what eventually becomes of the 88 computer and wiring, are they needed to control anything else? (I am going with custom gauge panel)

Other than that I learned I will need the motor mount adapters, flexplate adapter to run 700R4, harness, computer, different fuel pump, exhaust,... Cant think of the rest at the moment.

Thanks for any help. It is getting extremely confusing learning this swap. It seems like I am making ti harder on myself and seem harder than people say.

i believe that an SS is considered a light duty truck, so a 6.0 out of one of those could work. but i believe some of the newer "vortec max" 1500s had a 6.0 as well. so as far as trying to pass off a 6.0 as a motor out of a light duty truck shouldn't be a prob.

You won't need your 88 computer, at all. And you will need the wires that go to your gauge cluster. You also don't need the custom gauge panel, unless you really want to use it.

Yea I want to run a Nordskog digital gauge panel. reason being, I do not have any gauges right now and I am building a custom dashboard. I also got a good deal on the gps speedo for it so I dont have to worry about any speed signal from my 88 computer.

So considering I am going to be using this panel, when you said I need the wires going to my gauges, do you mean the original wiring or the wiring from the new truck?
Does the new harness come with the gauge wires?
