My first guess id the freeze plug behind the flywheel. 

It only gets worse guessing from there 

 

Unless there is a coolant hose in your swap at the top of the engine that is leaking. I don't k ow af an sbc with anything like that other than heater hoses in a factory application though.

Those carbs were known to be troublesome, but I have no firsthand accounts. Beware.

Which ones? I upgraded it last year so if you're speaking to the first one I initially had on the car it has been replaced and has run much better since last year when I switched over.

Unfortunately no other potential leak above that area that I could see. The oil definitely wasn't contaminated though as I just drained it and it was clean. Guess I'll start pulling parts off.

Sorry I missed that, it was the BG carb which I was referring to.

Leave the oil pan on for now. Just take the engine off the transaxle to access the core plug.

It has been a while. Car is running great, which of course means that I'm debating putting in an LS motor. Regardless, took it out a few weekends ago and got some cool pictures I thought I'd share.
