LS3 Swap questions ok im about to start piecing together an LS3 swap into my SS...i already have most of it the only thing im needing is the block and a few other tiny things like injectors and an intake and such....has this been done? i have a list of questions that i need answered and hopefully i can get them on here
i have heard the knock sensors are different..how can i go about that?
any other sensors that are different and i cant just swap over?
What can i do about changing reluctor wheels to work with my LS1 sensor and computer?
Will my LS1 fuel rail fit on the LS3 intake? gonna have to buy aeromotive or some such??
Tranny bolt straight up?
Throttle body setup???
Exhaust wise...can i use some LS7 Manifolds and get them to work with my FBody catless ypipe?
LS1 water pump bolt to an LS3 block? much less will all my accessories bolt up?
any other input on anything i havnt listed please let me know...im going to be selling my WHOLE LS1 longblock out of my car if anyone is interested also only 23k miles

Cam sensor converter, knock sensor extension harness, reluctor wheel converter.
Yes.
You need to run a larger throttle body that will fit on the LS3 intake. You can use a stock LS3 unit if you convert to drive by wire, or you can just get a good aftermarket cable driven throttle body.
Search the site heavily, there are a few of us that have LS3 based fourth gens. Good luck with you decide on doing.
