MHS 2V 5.4L PI Street / Strip Camshafts

5.4L 2V PI N/A Street / Strip Cams

The exhaust duration is made shorter on PI head N/A cams as the exhaust port, be it stock or ported, is highly overactive compared to the PI intake port. These are street and mild strip cams designed for 5.4L Engines with PI Heads. All of these cams can use the stock valve springs. 5.4L PI Engines have much more freedom with designing a N/A cam as the piston to valve clearance is a full 0.1" larger than a stock 4.6L PI Engine, so these are slightly different than their 4.6L counterparts. The exhaust duration is made shorter on PI head N/A cams as the exhaust port be it stock or ported is highly overactive compared to the PI intake port.
