Just guessing HP could be anywhere from 390 to 430 max 450. This depends on you altitude from sea level.Also density altitude on a given day.
 
If you got 450 HP out of it at adjusted altitude, that's pretty good. Of course it all depends on where you are in Colorado.

I believe most people when talking hypothetically horsepower like we are here, we are speculating on it’s possible corrected engine dyno hp which has the most meaning for comparative purposes.
 
We ran a similar combo in my sons 65 plymouth. The main difference was stock bore 440 with just under 8-1 compression. Mopar 484 cam, Eddy heads, Eddy performer RPM intake, 600 Eddy carb, headers. With the stock 12" converter, 3.91 gear, 255/60 BFG Radial T/A's it went a best of 12.88@110 here in Michigan.

Without doing the math I’d guess that’s close to 450 hp in a 4000 lb car in decent air (1000 ft DA)
 
I was at a friend's place when he ran his newly built 426 Max Wedge on his dyno. 465 h.p., 510 torque through factory exhaust manifolds. This is going into his '62 Dart 440 clone. Yeah, he has his own dyno in his shop! I figure H.P. for this poster's engine at 440-450.
