So I'm thinking of putting together a motor for a friend:

- 5.3L Block
- 6.0L Heads
- LS1 cam
- Stock cast pistons
- No bore (New block)

What kind of compression would I be looking at?
Mind you, this is a just an experimental motor so no trying to steer me away from it (i.e. "Just build a 408").

 

compression will be way low, going boost??
