Tasca has a 2009 mustang GT and a 2008 F150 5.4 3V as having the same part #'s for camshafts, they have a different part # for 2009+ F150's for the right side but the left side part # is the same across the board.
pretty sure the only difference on the motor itself is the intake manifold. Changing the least amount of parts saves the most money on production. especially when you already have a setup that passes emissions.
