@nm9stheham, I think you may have mentioned on the Speedmaster thread about checking the deck clearance, and low and behold there is .015 difference per side. One is at .010, the other at .025, and that's checking 3x and zeroing accordingly each time. So is this typical in production motors?
Maybe not typical, but that amount of difference has definitely been reported here by some of the professional machinists. That''ll make about .3-.4 point difference in compression ratio one side to the other. Not great but not a disaster IMHO.
I'd take a closer look at the 6th lobe from the back on the cam. Can't quite tell on that one. The surface rust on the cam may be an issue..... I don't know how you get it out of the pores without effecting the lobe surface. And since it is an abrasive, that does not bode well unless it is all removed. I am not sure if the resulting compound when using a rust neutralizer is any less abrasive. I personally would not use it unless I had to. New flat tappet cams don't cost an arm and a leg....
ON the top crank pix, is that some sort of metal inserted into the middle area of the front counterweight? How about rust/wear in the lifter bores?
