ls1 in a 03-07 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

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
