So you've already fitted the 24x crank reluctor wheel. 12559353
For that you will need the black crank sensor. 12560228
Your car might already have this.
Cam gear 12576407
Cam Chain Damper 12588670
You need to use the black one in conjunction with the earlier LS2 cam gear.
Cam sensor, you can use the one that came fitted in the 2007 LS2 front cover.
Cam sensor wiring extension [Caspers, Racetronics, Katech and others]
Knock sensors LS1 type 12589867
Open up the LS2 knock sensor bosses to M10 and screw in LS1 sensors
Knock sensor wiring extensions [Caspers, Racetronics, Katech and others]
MAF sensor wiring extension [Caspers, Racetronics, Katech and others]

If somebody had to buy a new cover it's probably best to shoot for the one with the technically correct cam sensor in it. (If that part number is even still available).
But the 2007 LS2 front cover with the 4x cam sensor will work with the old 2005 LS2 2x cam gear.

Bump too an old thread. This is the case since we ordered one that now you get the 325 cover so if this is the case is it giving you the 4x cam sensor too?

This timing cover+sensor part number is now superceded.
New LS2 front timing cover+sensor Part No 12600325 comes with a grey cam sensor.
This will work with 2005 LS2 cam sprocket 12576407 and produce the same cam signal as an LS1 would.
It will also work with a 2006+ cam sprocket 12586481 and produce a 4x cam signal.

I have the 2003 SSS LQ9/LS1 computer with a LSX 427 24X relucter what cam sensor do I need the black one or tan colour ?
anyone also notice that the stock LS2 cam chain is on the loose side or do I need to use a chain damper ?
couldnt use a double chain on the LSX block as it hits the cam plate bolts errrrr
also bought the casper knock and cam sensor harness but noticed that the cam sensor wire colour codes are switched around at the top conector do you guys think this is a F@$!@k up or to correct something

OK, if you put an ls2 in an F body you will need the LS2 timing chain and gear set, the ls2 timing cover 12600325 (the cam sensor that comes with the cover will work with the cam gears and the ls1 PCM) and you need to use the ls2 timing chain dampener 12588670, along with the wire extensions. Is that right?

You also need a 24x reluctor on the crankshaft and a black crank sensor.
