Performance Rocker Arms
Pushrod engines new and old are still a hot topic. Overhead cams have been used in many European and Asian engines for years, so when Ford opted to go the overhead cam route with their 4.6L V8 engine, some predicted pushrod engines were on their way out. But, GM stuck with the pushrod design for
Diesel Cranks and Connecting Rods
The demand for mid-size diesel performance products continues to grow. There tends to be two sides of the mid-size diesel spectrum: on one side there is street performance and on the other there is all-out race. Street performance diesels deal mainly with engine parts that are primarily for bolt-on applications and can make great power
Cylinder Head Porting
Huge flow numbers may be impressive, but optimizing airflow at mid-valve lift is key to power. If airflow though a valve port is plotted on a graph for the entire valve cycle (from opening to peak lift and back to close), the area under the curve is total airflow, which corresponds to total power. So
