I have an 09 Z06, buying and installing an LS7 engine from an 07 Z06. What changes will I need to make, reluctor? fuel system and injectors? etc.
Thanks

All the LS7 engines use the 58X reluctor wheel. IIRC, the 24X was discontinued in LS engines after 2005. The 2005 should be the only C6 to have it.

I don't think there were any changes to the LS7 between 07 and 09. Others will likely chime in, but you should be okay.

Some of the early 07s had the rocker arm trunion problem. If engine has any miles, they are probably OK..

Definitely a 58x reluctor. Pop the valve springs off and check for excessive valve guide wear. They were notorious for it. It's an inexpensive fix, and can save you many thousands of dollars.
