Definitive 2 or 4 bolt main exterior ID?
The block I have says 80-85 2 or 4 bolt mains according to Mortec.com
I have heard the 2 or 3 freeze plug method, but it seems like I also heard that this method is not reliable either. Is there any way to tell for sure?
casting number is 14010207
The engine is assembled for now, and I'd just assume leave it that way until I decide what I want to do with it. Which means not pulling the pan...
