Default Engine code 4bolt or 2bolt

When I pulled up this number unless I made a mistake it said the engine was 300 or 350 HP

But my engine builder just called and said it was a 2 bolt main block,
I am confused I thought all factory 300/350 HP engines were 4 bolt blocks?

Thanks!

The difference is in the machining...not in the casting.
