With all the talk about the 90mm throttle body from the LS2 doing great things for the Radix'd trucks got me to thinking. How hard would it be to swap in the GM LS2 crate engine? I know there's some tuning issues that need to be worked out on the newer LS2 powered cars, it seems that the (my) 04 pcm should be able to be set up to run the newer engine. Am I missing anything?

 

It should be a fairly straight forward swap. Only a couple of items have changed. You'll need to relocate your knock sensors and run a LS2 cam sensor. Physically it will bolt right in place of your current motor.
