the reluctor wheel is a 58x instead of a 24x, so you can either pay someone to put a 24x reluctor wheel on the crank, or get Lingenfelter's conversion box.
Unlike the LS1, the LS2's knock sensors are mounted on the side of the block.
I'm sure I'm forgetting things

ive been looking around and the only thing i have found was a corvette lt1 to ls1 swap. i was hoping to find a write-up or at least someone that has done the swap just to get an idea if it would be worth doing that or just fixing my lt and rolling with it.

Psssh, you been saying that forever.

OP, there are only a few things different as me and a buddy are doing basically the same swap.

1. Crank reluctor wheel is the 48 tooth instead of the 24. You must run the newer sensor.

2. Crank is 4x reluctor instead of 2x and its on the front timing gear (not the back under the intake). You must run the newer front cover with new sensor and new timing gear to make that system function. You must extend the harness as well.

3. You need the LPE conversion box to dummy down the signal so the older computers can read the signals of the new sensors.

4. Knock sensors are the same but located on either side of the block not in the valley cover. You must extend the factory harness to reach.

5. The valley cover is different. You must run a Gen IV valley cover.

6. You can run Gen III or IV heads but the intake much match them, i.e. cathedral with cathedral or square port with square port.

I dont think that stuff will work with a LS1 PCM..he may need to go to the LS2 Factory stuff..

He will be fine with the 58X reluctor wheel b/c he's gettin the PCM and the factory wiring harness from me as well. He will be getting a complete LS2 with all accessories from oil pan to intake, belts to flywheel. Including all sensors. Now what we r tryin to figure out is how hard is it to drop the LS2 in place? Steering shaft r rack and pinion be in the way? What about crossmember? If the crossmember is in the way, could we pass with the C6 rear sump pan? How about the motor mounts?

Steering shaft and k member have to be changed over to the LS style. You may need the LS cross-member for the trans. You cant run a C6 pan in an f body. You have to run an f body pan. Motor mounts need to match the k member, LS type.
