LQ9 has flat top pistons and the LQ4 pistons have a small dish to them. The differences in the pistons give the LQ9 a 10:1 compression ratio while the LQ4 only has a 9.4:1 compression ratio. Both engines have 317 heads (except earlier years) and *I THINK* the LQ9 has stronger rods. Not sure about that....
