Any one interested in the oiling mods I did?

Note that his r3 block does not have the counterbores in the saddle, why is that? Sanborn used to mill his bigger than stock.

That’s a good question. I think the feed holes are much closer together on that block. Tonight after it cools off I’ll go out and look at an OE 340 I have out there and see how far apart the feed holes are. It’s hotter than a popcorn fart here today and I’m staying inside until it cools down a bit. The dogs even have to wait for their walk.
