The performance increases generated by the Ford XFI Stroke Camshafts are the result of extensive engineering research, backed by dyno and real world testing. The engineering involved in the creation of camshaft profiles for 4-inch bore, 3-inch stroke (found in the standard 5.0L engines) is well documented. However, to produce an optimized stroker camshaft requires more R&D than simply increasing lobe profile duration to take advantage of the increased displacement.
The piston velocity in an enlarged stroker engine is greatly increased, resulting in an intake charge "event", which continues even further past the point (normal camshaft profiles close the intake after BDC - but in this case, the intake closes even further than normal) of Bottom Dead Center (BDC). To make more power from stroker engines, the camshaft timing of the exhaust valve opening is moved earlier to reduce the pumping losses, which are much more dramatic with these longer stroke applications.
Key Feature:
- Two camshaft profiles engineered to make more horsepower and torque
- Improved throttle response and increased engine vacuum
- Designed for use with component technology, such as 249-26120 Beehive valve springs
- The perfect combination for any Ford engine builder contemplating increased stroke displacement
