Guess the horsepower

Bought this , won't be able to run it til next summer , take a guess at horsepower just for fun
340 bored .020" over
10.5:1 speed pro hyperutectic pistons
Racer brown solid cam, .520 lift, can't remember duration but it's a lot
360 j heads fitted with 2.02/1.60 valves, ported and flow tested (255 from on intake)
Titanium retainers
Victor jr intake
273 rockers (adjustable)
Windage tray
I think the crank is turned .020" on both mains and rods
The engine will do the 7000 rpm.
