Wouldn't full groove mains be a lot easier ? All rods would have full pressure all the time.
As I've said, you can use full groove bearings. But you never get full pressure, full volume to the rods unless the hole in the block is lined up with the hole in the crank. The oil is also not there at the right time.
I realize most people have no idea what oil timing is because the book writers, and even Chrysler never put it in print.
It's real, it's required and the engineering is sound. Chrysler got it wrong for manufacturing sake. And not to dump on them, I doubt that when this stuff was engineered anyone ever thought guys would be making 2 HP/CID at 8000 plus. So you can't really fault them when you understand why they did it. Simply because it was easier to do it the way they did.
I also said the crank feed hole was at about 10:00 but I went out and look edits actually closer to 11:00. That's still a long way from NOON. And at 7500 or more, think how fast the hole in the crank goes by the hole in the block. I used to have the time figured and written down. I can't find it, but I can tell you it was something like .00000000012 seconds at 8500 or some crazy number like that.
