The number of stars indicates the number of casting packages purchased by the engine builder. A casting package is a bare block, pair of bare heads and an intake manifold. 1-4 casting packages = 1 star, 5-9 casting packages = 2 star and 10 or more casting packages = 3 stars, The number of stars is not a rating of ability or experience, simply a measurement of casting packages purchased.
