I have a 6.0 block with a fresh crank and mahle forged pistons, and complete 5.3 with ls6 cam, stock heads with comp cams 918 springs, ls7 lifters, and comp cam push rods. i am swapping one into my 04 colorado and want to run a little while N/A and then later boost it.

So my Questions are:
can i swap the 5.3 parts on the 6.0 block?
would it raise the compression?
Should i just drop the 5.3 in it as is and build the 6.0 for boost and swap it in when im done?
i will probably come up with more questions but thats it for now, thanks!

Drop the 5.3 in the way it is. Save 6.0 for the build.

I would use the 5.3 for now, and build that 6.0 for boost. In the end you will have 2 engines instead of on also.
