well, sorry to say, but the cam from a lightning will not wor in your 96 f150. you know that you have a roller ca, but the lightning never came with a roller cam, why that and mass air, i will never know. your best bet would be to use a Ford motorsports cam, such as an E303, f303, etc. i am using an E303 in my 95 f150, but i am currently changing over to mass air to handle the changes of the heads, intake, cam, etc. sorry, but the cams will not interchange, they will, but i would not trade a standard hydraulic for a roller. any other help, let me know, good luck.
