Small cam
Whats the smallest cam that ever was available in a FE motor? I pulled the intake off the 1969 390 in my truck. Measured lift at the lobe and its only .216"/.225". Verified it on another lobe too so the cam's not worn. By my math that's .374"/.389" at the valve. Tiny. Even a Autozone replacement has more lift than that.

A quick Google search on "FE camshaft specifications" shows the smallest lift was an early cam ('60/'62) at .232 lobe and .401 valve. That's .016 more that what you measured. I'm not sure if the cam would wear that much or not.

Measurement is accurate. Used my cam degreeing dial indicator and magnetic base. I hadn't planned on swapping in a new cam. I just needed to fix an oil leak at the back of the intake and was going to install a 4bl aluminum intake and headers at the same time. I have it this far apart so I guess I'm doing a cam swap now too.
I've got a 390 in my '66 truck and would be interested in how the mods work out for you... keep us posted.
