300 HP out of a 318, is it possible with bolt ons?

Obviously these articles like a lot of car TV shows are just basically commercials, and companies like Comp cam, Holley, Edelbrock sponsors, give free parts to these shows, just so these brand names are gonna be in the forefront of buyers minds cause there use in every build or show.
Doesn't mean the results are fake.
Oh no, results aren't fake. Fudged maybe, but not faked. 400HP 318 flowing just 215CFM on the intake port? I just don't buy it. No doubt the thing screams. I don't deny that one bit. But I'll never trust any TV show or magazine article seemingly pushing parts from their sponsors.....and they were doing that, even if just a little. Now, if they would throw it in a 3400 pound Duster and run the number, then I might be on board.
