The SBC and SBM crank oil holes are identical, Hmm. So senses the right and left banks are 90* apart it would be hard to oil them from the side of the block or from the main caps, you would have to do them both. The left bank you could do from modifing the stock oil hole, the right bank you would have to modify the main cap and bearing. Drilling the cap will definitely weaken it so I would use a steel cap.

Hell, you did most of the work for me!! THANK YOU.

Now, if you can, grab a SBM and a SBC block and show where the oil feed hole in the block is.

You will note that at ~70 degrees past TDC, the oil hole in the block and the oil hole in the crank will be lined up on the Chevy. On the Chrysler, the oil feed hole in the crank will be PAST the oil feed hole block. That means that full pressure, full flow oil out to the rods was way too early.

If you can post some pictures it's pretty obvious what is wrong.

And, it's not really and issue until you wind it up or throw a big load of nitrous or boost on it. Then it will rear its ugly head sooner.

The picture of the big block above is pretty close to what I ended up with. The first system was all in the pan. The second system was external like the one above except I had bulkhead fittings in the pan so I could run lines to the bottom of the caps. That, and cross drilling corrects the oil timing.
