As usual, lots of work, little to talk about.

Since my last update, I've gotten the front clip (mostly) re-installed - still need to pick up a few bolts to replace rusted. With the valves adjusted and the exhaust leaks fixed, it is MUCH quieter.

Oil pressure is a little lower than I would expect for new rod bearings - 30 psi at 30 mph, gauge appears to be just above 0 at idle. Seems lower than it was before, but maybe I'm just mis-remembering. I'm planning on putting a tee on the block and doublechecking with a modern mechanical gauge before I get too excited.

Still some fine tuning to do, but it's getting close.

I was getting a very strange rattle, only at certain rpm and throttle combinations. I think it's where the exhaust pipe was hitting the splash shield. The exhaust pipe was too long on the vertical section where it exits the exhaust manifold, and this drove the exhaust pipe into the splash shield. I'm having a local shop take 3/4" out of the pipe today, and hope that will fix my rattle. That is the second thing I've had to fix on my Waldron exhaust. The supplied tailpipe ended under the trunk, and I had to get one made that was 12" or so longer.

I'll post pictures of the wear spots on the exhaust pipe when I get it back.

I think I still have a little tick - maybe one valve not quite right, or the fuel pump arm, or I didn't get one of the lifters quite concentric, but I need to get some miles on it, so I think I'll let it be for a little while.
