It appears to be a combination of slight run-out (i.e., the cam is slightly bent, 1/1000 of runout in the middle), journal size right at the factory maximum spec, and installed bearing I.D. that is at or below the factory minimum I.D.<div><br></div><div>It's also possible that the block is not bored perfectly straight as the binding is not consistent around the rotation, but another cam I have, with journal diameters 5/10,000 smaller, turns freely. I have not checked that cam for run-out.<br><div><br></div><div>Question is, is there a tool to "expand" the bearings into the block and possibly gain a bit of clearance? I'm told the factory manual for one of those Octagon cars calls for such a tool. I'm using the typical Spitfire bearings.</div><div><br></div><div>Next stop is a machine shop with a crank straightening machine to see if they can use it to straighten a cam.</div><div><br></div><div><br></div><div><br></div><div><br></div></div></body></html>
