Horsepower guesstimation?

Ok. I looked back through all the parts orders and maintenance/service records and confirmed the following.
Hooker headers
Edelbrock 1405 600cfm 4barrel carb
Edelbrock 7176 rpm manifold
Isky racing cam isk-160171 with new hydrolic flat tappets. Duration is listed 270/270 lift is .465/.465
Compression was tested on the rebuild at 9.0 - 9.2 to 1
Does this shed any more light to the guessing.
Thanks again for playing.
