i have an old service manual that states .014" intake and .018" exhaust checked cold. that is for a stock cam. what brand is your cam? it may need more than this. is that advertised duration or 050"duration? whats the lift?
I have it in my 56 bird have over 8k miles on it. I've been working with it for six years now and notice increase in mpg and lots of power out of it. I would like to hear what others have to say about it.
