408 horse power?

I figured the lack of cam specs would hurt my question
Comp cam part number 20-224-4
Grind number : crs xe274h--10
Gross valve lift 0.488 on the intake and 0.491 on the exhaust
106.0 deg centerline
Springs are 995-16
Heads are 1977 360 truck heads polished and ported 4 angle valve job. I used 30. Deg. Intake valves instede of 45. Deg. For more flow. About 72cc chambers after milling the heads.
That's all the specs I have for now.
