This is definitely not a shoestring budget one but darn they are pretty when decked out. 409 high deck truck block with a 454 crank makes it a 503ci but what really makes a "W" engine come alive is to completely change the rocker arm geometry and DECREASE the exhaust port size. Many hours spent on the flow bench with this one because they were terrible from the factory.
