Should be plenty. I use a min of one thou per inch journal diameter.

Lots of good information here. You may want to consider installing a 15 lb. pressure switch coupled to the ignition to kill it in the event of a low pressure situation. CMcAllister is correct. At your clearances if that is what they are, at 40lbs of oil pressure, it would not hurt itself at 7000 RPM's. Keeping oil on it is the key. So as CMcAllister was saying, excess clearances and lifters/rockers, etc... add to low pressure situations. So a low pressure switch hooked to the ignition, will be a safeguard. Hope this helps.
Thanks,
Vance

Send me your email address, My dad did a ton of testing when the X block was developed, I have a list of stuff to drill out on the block. If you would like to talk to Herb hisself I can get him in touch with you. Herbieamccomedy@gmail.com Google A engine oiling mods herb mccandless. It may still come up. We drill almost every internal passage in the block.

Drilling passages to the mains, opening passages in the rear of the block, port matching the pump to the cap, massaging sharp corners, tubing the block (once, what a mess, just bush the bores), even fabing a dual pickup assembly were among the first things I tried. While they are, without doubt, beneficial, It didn't address the core problem, which is keeping oil on the journals in question. Measuring oil pressure at the port on the rear of the block tells you nothing about what is happening to the pressurized oil once it gets to the #2 and 4 mains.
