Two degrees advanced will aid in low end torque , may even provide a bit more vaccuum at idle . I ran this cam in a low comp. 360 Auto , you definitely need 4.30 + gearing and a good 3500 stall convertor . Ran the cam both str. up and +2 deg. I didn`t see a lot of difference , but your comp ratio`s higher . Good cam , should run good for you.
