LS9 (ZR1) Cam: 211/230, 0.562/0.558, 122.5 deg
LSA (CTS-V) Cam: 198/216, 0.480/0.480, 119 deg Biggest differences between LS9 and LSA, other than cam, is 2.3L SC running at 10.5 psi on LS9 and 1.9L SC running at 9 psi on LSA. Both have 9.1:1 compression, both run heads based on L92 design (LS9 could flow slightly better or maybe cool better - anybody have info on heads?). Both have forged cranks but LS9 has Titanium rods and forged pistons while LSA has powdered rods and cast pistons (like LS3, though LS3 has cast crank too).

Oh - also, the main caps on the LS9 have are doweled, and forged, if I'm not mistaken, while LSA is not; same block, but some subtle differences.
