Default 427 oil leak

Battling an oil leak on my 68 427. This is a freshly rebuilt motor. Zero miles

Doesn’t leak immediately on startup but once the engine warms up I have a fairly steady drip/almost stream coming off the bottom of timing cover/oil pan. Difficult to see because it’s also sort of spraying out with the air from the fan.

question- do big blocks have the hole that goes thru for the fuel pump push rod like small blocks? I don’t have any bolts in there because I didn’t think big blocks had that hole

Here's a photo of my '71 big block from when I removed the original timing chain set. Both holes on the passenger side have no bolts.
The driver's side uses the holes for the lower power steering pump bracket.

you could take the fan off. Can’t run long but it will warm up quick.
