The C5 computer will work fine, we have these in stock in 24x setups specifically for you guys. You'd just need a good tune.
Most everything will swap over from your existing vehicle. Exhaust, accessories, water pump, oil pan, coils, flywheel/clutch etc. If it's in good condition (not needing replaced anyways) and suitable for your newfound power (clutch), swap it over and use it.
You will need:
Intake setup completed with fuel rail, injectors, and TB of your choice (Nick Williams or LS2)
Injector adaptors
Your balancer will work if in good condition, also consider a new one while you are in there or even an aftermarket underdrive balancer.
To drill and tap for your knock sensors on the side of the block. New harness included with the engine.
I wouldn't consider running this engine with your factory exhaust manifolds. If you don't have them already, please get headers.

Jesse two questions: you said we would have to drill and tap for two knock sensors, how, where and why aren't they already there; second I noticed you said a new harness is included, is it complete except for the ECM?

The harness included is just the extension harness to use the cam sensor in the front cover and the knock sensors in the holes noted in the picture above. The holes are there, but are threaded for the newer Gen IV style sensors, whereas anything Gen III needs to adapt it to use their knock sensors.

Two questions.
#1 Is this still available and #2 would it be pretty straight forward to install into a 2007 C6? Thanks for the help!
