And the rest of the block stuff:
Here's one of my intake ports, it's a lot cleaner cast than the D16A1 head by far:
Here you can see the oil pump taken apart:
... and in this well-focuesd and -centered picture you can see the "T" where the two bores meet in the exit to the pump. This corner will be filled with epoxy or JB Weld, I'll open up this port a bit and smooth the transition out.
And finally, I opened up the main bearings like I said before. I fitted a drill bit into one of the holes in the girdle to get the right size, then held the bearing flat on the drill press with a small vise, open side down. This way the bore would match up with the vertical bore of the girdle and block's passages. Here you can see the unmodified bearing on the left, a hole in the girdle, and the opened bearing on the right. They match up perfectly when installed, but I have to clean the edges of the holes up from the drilling, there can't be any rough edges. Any suggestions? I was thinking about using a circular file.
