Horsepower guesstimation?

Hi everybody.
I'm new to the wonderful world of classic mopar. I have been looking up stats and horsepower and was wondering how much power is under my hood on my new favorite ride. I was going to dyno her to just know for sure but wow that's pricy. So I'll list what I know about the parts I have on her and can one of you who may have the same or similar setup give me a best guess as to the power. Or is this a silly request not worth discussion.
The goods:
1972 dart swinger:
Original 318 v8 .030 overbored on recent rebuild. Less than 10000 miles.
Hooker headers
Eddy 650cfm 4barrel
Hydrolic lifters replacing tappets
Electric spark upgrade.
New dual exhaust with flowmasters.
Mild cam.
Lightweight springs in the upgraded rotor and with excellent timing adjustment and tuning
15" centerline wheels
She wont really burnout due to freeway gearing in the diff. But has terrific boost after 30 mph.
I plan on eventually replacing the tranny with a rebuilt 727 that came with the car but I need a new driveshaft rear axel and diff to make the magic happen.

Any wisdom would be appreciated.
Thanks for listening.

Here she be!
