Are the Edelbrock heads Performer RPMs or Victor Jrs? If it is performer RPMs there is NO WAY it is making 450 HP at the wheels.

I am reminded that during the late 60's there were 3 kinds of horsepower quoted: At the tires, At the flywheel, and At the brochure. This sounds a lot like the latter.

With a 347 with ported Victor Jr heads, Intake, and a bottom end and cam capable of safely turning 7,500 RPM, it would be possible, but you would have to be pretty hardcore to call that a street engine.
