All righty than.
Assuming Rat is correct and the cam has 4* advance ground in.
And you installed it adding +4* of advance
That would mean you have the cam in @ +8* advanced cam timing.
If true, the question then is what will this do to the performance?

If one degrees the cam in during installation, then all possible variables would be eliminated........ and you’d know where it was installed.
