HorsePower Guess???

Posting this for a friend, he just bought an 87 camaro, with a supposed recently built 355 motor, all he knows it has stock camaro 305 heads (been ported and rebuilt), it has a .488/.488 lift cam, flat top pistons, stock intake manifold, edlebrock 700 cfm carb, he has a 350 turbo with a shift kit and 2500 stall. He has a posi rear-end with 3.73 gears. Basically he is curious to how much horsepower this car is putting out, he isn't ready to take the car to a dyno so.. The previous owner told him the motor puts out between 350-400 hp. So any guesses on how much horse power this thing puts out.

Duration 292/292, Lift .488/.488 I believe that is the stats on the cam, he also has shorty headers and a full 3 inch flowmaster exhaust, no cat with an electric cutout.
