I received a 1981 f150 w/300ci inline 6. The guy I got it from bought a bunch of new parts including a new cam and lifters. I'm to the point in my engine build that I need to set the valve-to-rocker arm clearance, but I do not have a cam card to set the suggested clearance, I am pretty sure the cam is just a stock replacement so nothing special about it, what would be the clearance for the stock setup for this engine, I feel that is the best route to take, any info will be appreciated.

 

The info you need is here...

Be sure and read the whole thread.

Short version; If you have bolts that hold the rocker arms on, your valves are not adjustable. If any valve/head work was done and done properly, just bolt everything down and go.
