How much horsepower does this have

As most of you know by now I’m not much of a believer in dyno horsepower and have never used one. But my sons stock crank 360 was an engine that always impressed me for the parts used. We are limited to 1/8 mile times in our class at all the tracks we run at but his car has already turned nice 1/4 mile times, probably because of the 4.10 gears
