Get under the car and see if it comes out from between the bellhousing and the block area. if you clean the sides of the bellhousing and make sure no oil is there you will know immediately if its the rear main. Lol

You sure yours its the rear main? They generally get progressively worse and I have never seen a rear intake only leak a few drops. Lol as you mention it has various leaks, a few drops is small.
Yeah did the wipe test, and its the rear main.

I have never believed a dyno sheet in the last 40 years without the current baro, air temp and humidity along with raw data and dyno correction factors.
