static and dynamic compression and pump gas

Ica of 69 is the 20-601-9 cam, in at 103.5. (291/311/107 advertised)
On the 107LCA, that is ~4* advanced. The 69* is just what I had to input into the Wallace to match OPs numbers back in post #1, which were 159psi/7.89Dcr,and 10.37Scr@300ft elevation

Where does the 54 come from?
