Airflow is where the power is, and for the money, it's impossible to beat the performance of a set of GM Performance Part iron Vortec heads. Taylor elongates the pushrod holes inboard to ensure no pushrod interference when using the Pioneer 1.6:1 rockers.Airflow is where the power is, and for the money, it's impossible to beat the performance ConclusionEven with the new parts we used, you could duplicate a similar long-block with Powerhouse parts (including the Vortec heads) for well under $2,000. Crank in a bigger cam and the horsepower will climb, but it will also sacrifice torque. As it is, this is a great package with an idle vacuum of almost 13 inches at 750 rpm, making this engine very driveable in almost any kind of street application. There's never been a better time than right now to build a stout 375hp first-generation small-block Chevy engine.
