Default ls1 in a 03-07 Silverado

Alrighty so im considering taking my ls1 that i have sitting in my garage and dropping it into a silverado

Now i know the blocks are identical so it should drop in
but i have a few questions

what will i have to do to run a ls6 intake on it?
will the truck throttle body match up with the ls6 intake?
will i have to run ls1 front accessories or can i stick with the truck accessories?
will i have to run a new pcm and engine harness?
regular silverado headers would work right?

and what would need to be done if it was a 4.8L truck?

sorry im new to this and ive tried searching but there are no write ups, only references that ive found

I've seen guys use LS6 intakes with truck accessories. Ls1truck has an thread about swapping intakes

Unless you care about the weight savings, since trucks are heavy anyway, you might consider selling the LS1 and buying a 6.0. The difference in value could be used for some mods

I was told by Street & Performance the flywheel had to be changed out or the hole need to be egg shaped. I also have a fresh 5.7 short block laying around but people want it given to them as well....
