need more info on truck, if you want a good answer on cam, you keep finding ways to ask same question
According to the Haynes manual, the stock cam lift is .253 intake/ .278 exhaust. With the rocker arm ratio of 1.73 that equals .438 intake/ .481 exhaust. They don't give the duration figures.

I just got a new cam and bearings for my 93 7.5L. Are the cam bearings all the same size or is the difference so minute you cant see them with your eyes?
