Default 396 3935440 block help

Can you tell if a 396 with the casting 3935440 is a 2 bolt or 4 bolt main. Besides the main caps is there any cosmetic difference.

Jason

Thank you very much. I got a complete 68 396 with the chevelle I just bought and I just wanted to know if it was a 2 bolt or 4 bolt main without moving the oil pan. Thanks again

No problems Jason. So which one did it turn out to be? Two or Four?

How do you explain the fact that I have two 4-bolt main blocks with the small "oil holes" ?
This pic is from my late -69 4-bolt #512 block.
