Easiest way to see if its an aluminum block...will a magnet stick to it? If the answer is yes, its not aluminum.

To the best of my knowledge:

If it's an Iron block and has 6.0l on front of block:
LQ4/LQ9 - Gen III, cam sensor in the top rear of block
LY6 - Gen IV, cam sensor on the front timing chain cover

Aluminum Block and 6.0l on the front:
LS2 - Gen III, cam sensor in the top rear of block
L76/L98 - Gen IV, cam sensor on the front timing chain cover

On the LQ4/LQ9 the only difference is the pistons, so no visual external differences as far as I know.

Congrats, there will be a lot more parts than just the ones you listed! Was it a complete drop out?

I'm doing an LQ9/T56 in my '67 Camaro right now.

Not a complete drop out just the motor check it out. I have a 4L60E already cant wait to get some LS3 parts I'm doing research for a cam now
