The Blacktop head featured a wider flange experience to Permit these channels a strong surface to seal in opposition to.
All ECU’s use various sensors to find out load. Having said that the strategy made use of varies amongst engines since the Silvertop uses an easy Vane style airflow meter while the Blacktop takes advantage of a more sophisticated vacuum (MAP) and throttle posture (TPS) for bigger throttle openings the place there isn't any vacuum.
