Tore down the rest of the block. The bores and pistons look excellent.
There's some carbon buildup but nothing to worry about I think.

Cleaned up the crank in the lathe, still needs a final polish. Looking at having the rear main seal area spray welded up and then turned/polished to final size. There's pitting there that needs to be repaired.

Happy with how the cylinder heads look along with the Cummins diesel exhaust valves. Valve lash was always in spec and rarely needed adjustment so couldn't be happier. Still using the stock valve springs which have very little seat pressure I must admit. Not a problem on a low RPM engine though. I've looked around for stock valve springs that are comparable in size and have more seat pressure and found Ford 460 valve springs are close (MELLING VS840) I haven't tried them but they definitely have more pressure. Might switch the valve springs out when the new camshaft is broken in.

One is the things I wanted to make was an oil pan spacer. The longer stroke with the 305/pickup oil pan makes for a close encounter of rod bolt and sheet metal. Not ideal. I previously dented the oil pan to make clearance.
The real solution is that spacer. Its fabricated out of steel strips and then milled flat. About 3/8" thick. I did have some chatter while fly cutting it so I ground it flat afterwards. Should seal up with RTV to the block I think. Still using a cork gasket on the oil pan side.

Almost have the short nose high torque starter ready, will post my progress on that in the other thread soon.

The rod bearing clearance is way out of spec. Rods need to be resized. They aren't stretched or oblong or something, can't explain why there this way. Possibly it left the factory this way in '62. Crank (and main) journals are in right in the middle of spec. Again something I should have done the first time. Anyway, I'll be doing that, too.

Haven't checked main bearing clearance with the NOS bearings but think we should be good there.
