Stock vs. AccuFab Throttle- body and Elbow Installation of the Accufab 70mm throttle- body and elbow was worth a few extra horsepower when the motor was equipped with the stock cams, but the additional airflow required to feed the extra horses produced by the cam change made the stock throttle-body and elbow even more of a restriction. Adding the Accufab components resulted in gains as high as 10 hp. We suspect the Accufab components will be even more beneficial once we install the ported heads and PI intake. View Related Article
