I also did an oiling mod to the front main saddle. There are two oil feeds to the front main bearing. According to Timothy Meyer, the oil pressure issue with these engines will be greatly improved by blocking the one pictured with a 1/4" pipe plug, as I have done and enlarging the second to 5/16". This helps divert that extra oil to the rest of the crankshaft, as the Cleveland engine family does not have priority crankshaft oiling. I also have some Timothy Meyer modified camshaft bearings on the way that will divert more oil back to the crankshaft. They have grooves cut in the back to act as restrictors. Instead of aligning the holes in the bearings with the holes in the camshaft bores in the block, you position the holes at about the 3-4 o'clock position which covers the holes in the block and makes the grooves in the back of the bearings the path for the oil to take, thereby restricting the oil to the top and diverting more oil to the crank. This also puts more bearing material right where the bearings have the most load, right at the bottom. It places the oil wedge in just the proper place to give the best wear for the bearings. At least that's the theory.
Here's the mods to the front main saddle. You can see the plug on the right side. The left side comes from the filter and then right to the main lifter galley, whereas before, there were two huge oil leaks right at the front main. This way, there will be much less pressure loss and really no loss of lubrication. You can see the horizontal passage coming from the filter and intersecting with both the now larger 5/16" main oil hole and the plugged oil hole that now only feeds the main lifter galley.
