The cam swap itself is probably easier than traditional and the gains all depend on how streetable you want it, but suffice it to say, you can gain a lot and still be perfect on the street.

The LS6 intake is slightly better although keep in mind later (I can't recall exact years) LS1 engines came with both LS6 blocks and intakes so you may not need it.

The best thing to do overall is read ls1tech for a bit so you know what you can do and what to expect.

You are correct about the LS6 manifold, I did a bit more research directly after my last post. Initially it appears that my 02 SS Z28 donor camaro would have come with the LS6 mainfold and block. So now I need to find out "When is an LS1 an LS1 and when is it an LS6? Is it the cam/springs that make the difference....the heads...the tune....? The only thing I can say positively is that I have more research to do! I would give my right *^% to talk to the LS Jedi Master as I've spent hundreds of hours in research starting with the basics of Protouring.
