Modular Head Shop has been a leader in Camshafts for the 4.6L / 5.4L 2V Engines for quite some time now. We know what works, we know what fits. If we state there will be no Piston to Valve clearance issues, you can be assured there will not be as long as the camshafts are degreed properly. There are many Camshaft grinds advertised that state there is no PTV issues when in fact if those Camshafts are degreed to the recommended Intake Center Line or Opening Point, there will be PTV interference.
Our GEN 2 line of Camshafts has been in the works for the last 2 years and many of these lobe profiles have been tested on in house builds and have shown some improvement over our already proven Camshaft profiles.
All of the GEN 2 Camshafts are ground specifically to our specifications from COMP CAMS. COMP offers very short lead times and we try to keep the more popular grinds in stock. However, most of the camshafts are ground to order. If you are in a hurry, please contact us for a current lead time before placing your order.
