Mopar Performance Purple Mechanical Camshaft - P4120653AE Cam Card

Is there a way to calculate cranking cylinder pressure for this cam?
I noticed that the intake opens @ 13* BDTC is that at .050 ?
Looking at the cam data for a MP .528 cam the intake opens @ 32* BTDC
That's a big difference in the it's ability to build cylinder pressure.
To my understanding the earlier you open the intake the more pressure the cylinder will build.
I have a cam now that has a 9* BTDC intake opening and it low on cranking pressure and a dog out of the hole.
Not trying to be critical, just trying to understand.
I get ya there. You know who is good at this?
The calculator master @AJ/FormS can calc this one up for you right quick.
