Lake Speed's Ford C3 NASCAR Engine: NEW Comp Cam! 20+ Year Old Camshaft Specs vs Current Technology
What happens here
The discussion shifts to a newer camshaft design (Cam 2), highlighting its 'low-shock' characteristics. This modern design differs in its intake valve opening. While it starts opening earlier, the initial ramp-up is slower compared to older designs. However, it rapidly accelerates through the top dead center (TDC) region, providing a quick burst of airflow. This allows for a more controlled power delivery at the start and a stronger pull in the mid-range.
Goal: Understand the low-shock design philosophy and its effect on initial valve opening.
