De-tune 360 mag

I have a Crower 34116 hyd roller grind. 284@,[email protected] on a 114 lobe center. Had 21" at idle vacuum, @ 800 in drive.(carbed,16 initial).

What is the lift on that?
And what compression are you running.
Sorry did not look up the specs on the cam.
How does it pull down low 1000 -2500 rpm.
