Dropped the pan,
There was a big handful of rust in the bottom of the pan, but looking up at the crank and cylinders they look OK.
It will take some work to get it running, but so far it looks like I may be able to without a complete rebuild.
The dented oil pan looks like it was from a forklift, and never tried to run like that.
Next is to remove the carburetors one intake and one of the four heads. I'll take a look at the cylinders and decide if I need to pull all four heads.
I'll also remove a main and a few rod caps to have a look.
